Toronto police have charged two men in connection with a fatal double shooting outside Rebel nightclub on the weekend.

Abdirisaq Ali, 23, of Toronto, and Tanade Mohamed, 24, of Edmonton, were arrested on Monday and have been charged with two counts of second-degree murder each in the shooting, which took place in the parking lot of the Port Lands nightclub around 3 a.m. Sunday.

Police said when officers arrived at the scene, they found Zemarai Khan Mohammed, 26, and Tyler Mclean, 25, suffering from gunshot wounds.

Mohammed was pronounced dead at the scene, while Mclean died of his injuries in hospital.

Investigators say they believe an altercation took place sometime before the shooting.

A black vehicle was reported speeding away from the scene and was last seen northbound on the Don Valley Parkway.

'He wasn't supposed to be at Rebel that night'

Alexandra Mussakos, 22, had only known Mclean for three or four months, but says she spent nearly every weekend with him. She told CBC Toronto that he had just come home from a trip to Peru and hadn't planned on going down to the club.

"He wasn't supposed to be at Rebel that night. I think he just wanted to come see everyone," Mussakos said.

Another friend, Ivona Tymoshenko, 22, said she didn't believe the news of his death at first.

"One of my friends called me, and she told me how he died, and that's when it really hit," Tymoshenko said.

"Tyler did not deserve that."

Neither of the friends said Mclean was the type of person to be involved with this kind of violence.

"He wasn't an aggressive person, he was a happy charismatic person," said Mussakos.

"He never got into any fights, never caused drama," said Tymoshenko.

The family of Zemarai Khan Mohammed, who many knew as Amir, has set up a GoFundMe page to help pay to fly his body back to Afghanistan, where he came from six years ago, so he can be laid to rest beside his parents.

"He was simply an amazing soul that brought happiness into everybody's lives," the page reads.

"He was loving, caring, and generous with every single person that he met. To many of us, he acted as a caring older brother, always looking out for us and watching our backs."

'Stay low scumbag, you're arrested for murder'

CBC Toronto has obtained video of the arrest of at least one of the men accused in the double shooting.

Suren Sukiasyani shot the footage.

He happened upon the arrest on Monday night in the area of York Mills Road and Don Valley Parkway. When he saw the police with their guns drawn he tried to back his car up and leave but another car had parked behind him.

"I was stuck there. I figured I was safe, they're not bugging me, I'm not in danger," Sukiasyani told CBC Toronto.

"I took out my camera when I heard,'Stay low scumbag, you're arrested for murder.'"
