Bret Michaels is back in the news for all the wrong reasons - police reportedly found marijuana and unidentified controlled substances during a search of his tour bus in Indiana.

According to the Los Angeles Times newspaper, law officials pulled the vehicle over near Ashley on Wednesday night after spotting a broken brake light, and boarded it as the Poison star was travelling home.

Sniffer dogs tipped their police handlers off to the presence of drugs and the cops then carried out a thorough search, uncovering controlled substances.

Michaels' publicist says, "No arrests were made. Mr. Michaels allowed an open search of the buses and everything was handled in a professional manner."

Michaels is no stranger to the headlines in 2010 - he made news in April and Mayfor a series of medical emergencies, including a near-fatal brain hemorrhage.
