Police continued appealing to the public Friday for help in the search for a suspect in the murder of taxi driver Mohammed Nehar-Belaid.

The body of Nehar-Belaid, 64, was found in LaSalle Wednesday after he went missing Sunday.

His Ford Taurus taxi was last spotted at a Verdun gas station on Monday. Police released surveillance video from the station that shows a man behind the wheel of the taxi. The video shows someone driving Nehar-Belaid's car and using his credit card. Police said they want to talk to the person in the video, but so far, have only received a few tips.

"It would take someone who knows him to call us and give us his name, but we could have people who were there that night who saw that man, who saw that car, who have information they think is not relevant but any information, as small as it could be, could make a difference," said Montreal police Const. Olivier Lapointe.

Meantime, the mysterious death was still the hot topic of discussion and cab drivers at the St. Laurent taxi stand where Nehar-Belaid often picked up customers.

"He was very nice, very quiet," said Khalifa Maroun, adding that many of the cabbies at the stand got to know him well.

"It's terrible whatever happened. It's disaster. We have no protection. We have nothing. We are target to anybody. Anybody can come in the car and attack us or grab by the back," said taxi driver Emmanuel Elefthirakis.

Many cabbies said there are some safety precautions that could prevent similar cases, such as shields, GPS trackers, and panic buttons, but not all cabbies are convinced.

"I don't feel comfortable with that (shield). Nothing is 100 per cent, like they told you. They can come through the window, or when you're helping with the luggage. There's many, many ways if somebody wants really to hurt you he knows what to do," said cabbie Pierre Elias.

"The panic button, maybe it'll help but before you push the button, they can kill you or they can injure you," said cabbie Tony Kfoury.

Taxi drivers are awaiting details in Nehar-Belaid's funeral, but the coroner's office has yet to release the body as the investigation continues.
