A science student who forced a Manchester college campus to go into lockdown after he stabbed two other teenagers following a row over a girl has been jailed.

Mohammed Alsarayefi was just 17 when he knifed his victims in a fight outside the canteen at The Manchester College’s Shena Simon Campus after an argument erupted during a morning coffee break over a post he left on Snapchat.

A fellow student, then 18, had just read on social media that his ex-girlfriend was dating Alsarayefi and confronted him.

But he was left fighting for his life after being stabbed in the chest, back and upper arm. The teenager suffered a partially-collapsed lung.

A third student, also 18, suffered a knife wound to his back as he intervened.

The double stabbing, on November 11, 2016, led to an evacuation and lectures at the city centre campus to be cancelled.

Alsarayefi fled, but was later arrested.

Now, almost two years on, Alsarayefi, now 19, from Fallowfield, is behind bars having being convicted of two charges of wounding with intent to cause grievous bodily harm following a trial.

He was jailed for six years.

He was cleared of the more serious charges of attempted murder after jurors at Minshull Street Crown Court took five hours to reach their verdicts.

Friends and loved ones wept in the public gallery as Alsarayefi was led away.

The court heard the feud began after the first of Alsarayefi’s victims split up with girlfriend of two years after he accused her of having a fling with a different boy.

The girl, who attended a different college, then began dating Alsarayefi.

The 11am stabbing occurred when Alsarayefi’s two victims went into the canteen and saw him with the girl.

The girl’s ex said: ”This made me feel frustrated and I went over to speak to Mo [Alsarayefi] with the intention of having a conversation with him.

“I asked him to chat outside and he said ‘let’s go’. He acted friendly with me, but he was being fake. I took out my gloves because it was cold as we went outside. Mo then said ‘is this about me f****** your ex?’

“I felt hurt and I punched him in the face, but I saw a slither of silver in his hand, which went towards my chest.

“I tried to punch him again, but then realised I had been stabbed. I didn’t feel much as I was full of adrenaline. I looked down and my grey tracksuit bottoms were red and I clutched my chest.

”[My friend] was on top of Mo. I then saw him hit or stab him a few times. I shouted ‘call an ambulance!’. I thought I was going to die.”

The second injured teenager told the hearing: “[My friend] got up and walked towards Mo and then I saw the two of them walking out.

”He asked me to come with him, so I followed him as I would break up any fighting. I didn’t see who started it, but they were both punching each other.

“Mo looked like he was going to continue, so I went towards him and grabbed him his legs and he fell to the floor. But I felt a pinch to my back so I punched him and his head hit the floor and a silver object flew from his hand.

”I borrowed someone’s phone to call 999 and saw Mo run off. I then felt I had sweat on my back and it was blood.”

Alsarayefi, who was hoping to go to university after completing his access to science diploma course, denied wrongdoing arguing he was acting in self defence – claiming his first victim had the knife.

He told the jury of his relationship with the girl: ”We never slept together. I did approach [the first victim] and told him that I was seeing [the girl] and he said that he respected me for telling him and that I was a good lad.”

Alsarayefi claimed the girl had posted the story about them on Snapchat and then attended the college to see a friend.

He added: ”I did see when [the first victim] approached me that he wasn’t very happy.

“But I didn’t realise he would fight me, I thought that he would just get angry and raise his voice and then let it go. We had already had two civilised conversations before, so I didn’t realise that it would end in a fight.

“When he asked me to follow him out of the canteen, I thought he would stop at the stairs, but he continued outside.

”He then did a 180 degree turn and used his right arm to swing at me and I quickly threw my hands towards where he swung and blocked him. At that moment, I could see a knife in his hand. I started attacking [him] to protect myself.

“While being attacked, I managed to seize the knife from [him] and started throwing swings with both my hands.

“I am responsible for his injuries, but I never knew that I hit those spots. I was in complete shock and walked away and then I received a phone call from my father he told me that the police were at home and that I needed to come home.”

Sentencing, Judge Stuart Driver QC told Alsarayefi: ”This has had a lasting emotional impact on the two young men. There was a degree of self defence in that the victim swung the first punch, but to then to strike with a knife was wholly out of proportion.

”You were 17 when you went to college that day, armed with a very dangerous knife and you used it to inflict a very serious injury.

“The offences are aggravated by the location and time, outside a college when other young students had to see the blood and aftermath.

”If you had been an adult at that time in an identical circumstance the least possible sentence would have been one of nine years.”
