Greyhound has launched an investigation into the actions of an Alberta bus driver after a passenger's home video appears to show the driver using his smartphone behind the wheel.

Greyhound released a statement to CTV News stating: "This is a definite breach of our policy and something we take very seriously. We have identified the driver and are currently conducting an internal investigation where we will determine appropriate disciplinary actions.

Fort McMurray resident David Sabine took the video. Sabine says he initially wanted to notify Greyhound of what he saw, but couldn't get through to them.

"The Greyhound website doesn't provide any means of providing them with comments, so I posted it," he said.

One woman, who boarded a bus on Tuesday afternoon, says the video is shocking to watch.

"He's a driver, so he should be more responsible," said Kathleen Lavallee.

The recent riots in Vancouver following the Canucks' loss prompted police to use social media to catch those behind the violence.

One social media expert says the incidence of cameras in public and posting images for the world to see will only increase with time.

"This is something that can happen every day, all day long. People need to operate as if they are on camera at all times," said Walter Schwabe.

A former Alberta law professor believes it's likely the amateur video of the bus driver will be used to prosecute Alberta operators. Sanjeev Anand says more and more these types of videos will be used in all sorts of cases.

"I think in the future it's going to be the rare occasion when we don't see video evidence from a smartphone being presented in a prosecution."

Sabine says he hopes to now get a call from Greyhound, and some assurance something like this won't happen again. He has forwarded a link to his video to both Greyhound and to Transport Canada. He says neither have replied.
