Motorists in Indianapolis say a Comcast Xfinity repair truck is to blame for multiple slide-offs and a rear-ender on an icy roadway.

A video of some of the incidents, posted online Tuesday, shows cars sliding off the slick road as they swerve to avoid hitting the Xfinity truck, which was sitting at the bottom of a hill.

Some complained that drivers coming from over the ridge couldn't see the truck, and the four or five cones placed behind it didn't give motorists enough warning. Several cars slid off the road as a result.

In the video, which quickly went viral and had been viewed more than 700,000 times as of Thursday morning, a Comcast worker insisted he had placed the necessary number of cones.

Someone else ultimately put out more cones after the Xfinity workers didn't.

Comcast says the company is looking into the incident.

"When I watched this video I was very concerned by what I saw. Our employees should always protect people and treat them with respect no matter what the situation. Safety matters most - especially in dangerous weather conditions like this," Ed Marchetti, the company's senior vice president for technical operations, said in a statement. "We are actively investigating what happened when our technicians were on site to restore services during an outage and we will reach out to those who were impacted by this incident."

The state Occupational Health and Safety Administration told Indianapolis television stations that the agency was also investigating the incident after receiving a safety complaint.
