Indiana police found marijuana and other  unidentified controlled substances on rocker Bret Michaels’ tour buses,  The Fort Wayne News-Sentinel reported Friday.
Two tour buses, one of which carried the  rock star, were pulled over in DeKalb County, northeast Indiana, before  midnight local time Wednesday.
Police stopped the caravan because a trailer  connected to one of the buses did not have a license plate light.
Officers launched a drug search on the first  bus after narcotics-detection dogs reportedly began acting strangely,  The DeKalb Star reported.
Police then searched the second bus, where  Michaels was a passenger, and also found illegal drugs. The veteran  rocker was reportedly very cooperative in allowing the searches.
Police made no arrests but charges have been  forwarded to the DeKalb County Prosecutor's Office. Both buses were  allowed to continued.
Michaels, former frontman of rock band  Poison and the 2010 winner of the “Celebrity Apprentice 3,” is currently  on his “Roses & Thorns” tour in the U.S.
The 47-year-old recently overcame a brain  aneurysm and a “warning stroke” earlier in 2010.
