Four people were sent to hospital with injuries Saturday morning after a pickup truck plowed into an Edmonton bus stop.

The Ford F150 was travelling westbound on 107 Avenue when the driver "apparently lost control and went up on the south sidewalk and struck several newspaper boxes and then the bus shelter," Edmonton police Const. Gary Lamont said.

Three people waiting in the bus shelter were injured, Lamont said, "the most serious of which is a 74-year-old male who was taken to the Royal Alexandra Hospital. I'm told that he is going to survive but he's obviously pretty banged up. He's got several fractured bones."

It's not known how seriously injured were the other two people at the bus stop.

A passenger in the pickup was taken to Misericordia Hospital with minor injuries and released.

The man driving the pickup, 23, has been arrested and is being interviewed, Lamont said, and charges are possible.

"Right now we're not sure," Lamont said. "We need to talk to people who actually witnessed the occurrence. We have people that heard the occurrence … but nobody that actually saw him go left of centre, mount the sidewalk and hit the bus shelter."

Lamont said police are especially interested in speaking with the passenger in the truck, who was released from hospital before he could be interviewed by investigators.

"It's terribly unfortunate," Lamont said. "You think you're safe. The last thing you think about is being critically injured but unfortunately these things happen."

Police closed 107 Avenue between 115 and 116 streets as they investigated the accident.
