Lower Moreland Police Chief Pete Hasson tells NBC10 Medvedev was stopped for a traffic violation around 2:45 a.m. along Byberry Road in Lower Moreland.
The officer then arrested the 33-year-old Russian national for suspicion of driving under the influence, Hasson said.
Charges have not been filed in the case. Hanson said police are awaiting toxicology results. Medvedev has since been released from police custody.
Medvedev just wrapped his first year with the Flyers — and in the NHL — after a lengthy pro career in Russia. He was a fairly regular lineup presence in the first half but had his role reduced as the season went along, and ended up appearing in just 45 games.
Medvedev was then a healthy scratch for all of Philadelphia’s opening-round playoff series against the Capitals.
He’s set to become an unrestricted free agent on July 1.
