HAMPTON, N.H. — Ex-Poison frontman Bret Michaels says two thieves stole his cellphone while he was onstage during a recent performance in New Hampshire.

A post on Michaels’ Facebook page on Friday said the phone and other electronics were taken from the rocker’s dressing room during a concert at Hampton Beach Casino Ballroom on Sept. 1.

The post included an image of the two suspects and said that the items could be returned within 24 hours, “no questions asked.”

After the deadline passed, a post stated that the culprits would be charged with criminal trespassing and felony theft of property if they didn’t return the items to Hampton police.
