Aston Villa are launching their own investigation into Barry Bannan's arrest.
The Scotland international, 21, was arrested by police on suspicion on drink driving - along with Shrewsbury striker James Collins, a former Villa player - and subsequently bailed.
Villa have launched the investigation and Bannan did not train with his team-mates on Monday.
Aston Villa manager Alex McLeish said: "There are internal inquiries and an investigation going on and that's all I can really say at the moment.
"We felt it was best that he (Bannan) did not train with the team today."
