EDMONTON - Cops are looking for an Ontario man - a suspect in a gas-and-dash death - who allegedly pulled a gun on an Edmonton transit peace officer.

Police accuse Abdullahi Mohamoud, 23, a Mississauga native, of using a weapon to get the officer to release another man who was being arrested for trespassing at Churchill Station on New Year's Day.

Police later found the alleged trespasser but the alleged gunman is still at large.

"This is a very dangerous and violent person who needs to be taken off the streets as soon as possible," said Edmonton Police Service Staff Sgt. Malcolm Allan.

This is just the latest in a list of alleged crimes Mohamoud is wanted for across Canada.

According to police, he has a Canadian-wide warrant out for his arrest for criminal neglect causing death in relation to a fatal gas-and-dash in Mississauga, where a gas station attendant was dragged to his death on May 19, 2011. Hashem Atifeh Rad, 62, tried to stop the SUV before he was struck. He died later that night in hospital.
Mohamoud is also facing an aggravated sexual assault charge in Edmonton in 2008.

The most recent occurrence adds charges of uttering death threats, firearms charges and a charge related to helping in the escape of someone from police custody to the list.

Mohamoud is considered armed and dangerous, and described as six-foot-two and around 160 pounds.
