Langley and Surrey RCMP are hunting for the man who stabbed a stranger in Aldergrove, and is also thought to have strangled a bus driver in Surrey.

Serious Crime Investigators are looking for a suspect in the two non-fatal attacks. The most recent was the stabbing Tuesday of a 41-year-old man who was attacked while getting off a Langley-to-Aldergrove bus at 4:45 p.m.

The man was travelling with his brother, and neither of them spoke to the suspect during the trip, said Cpl. Holly Marks of the Langley RCMP.

The victim had just exited the bus when he felt what he thought was a slap on the back. He quickly realized he had been stabbed.

The man’s brother chased the suspect but turned around to give first aid to his brother.

The victim was airlifted to hospital for treatment and is expected to survive.

The victim didn’t know his attacker at all, Marks said.

Forensic identification officers gathered evidence at the scene after the attack.

This attack follows an incident Saturday in which a Coast Mountain bus driver in Surrey was choked.

The suspect got on board at about 9 a.m. and stood in an unsafe area. When the driver asked the man to move, the suspect did as he was asked.

However, at the next stop, the suspect choked the driver, one handed, for some time.

The man ran off, and police dogs failed to track him down.

The attack took place on a southbound bus that was near 76th Avenue and King George Boulevard.

The violent bus passenger is Caucasian, about 18-20 years old, stands 5’10 to 6’0” tall, and weighs about 150 pounds, and has dark hair.

Security with TransLink will be doing extra patrols in the coming days, especially around the Surrey Central and Aldergrove bus loops and exchanges.

Marks said a lot of resources are being put into the hunt for the suspect, with identifying the man the primary goal right now.
