Signed Michael Jackson shoes stolen from auction

Not the pumped-up kicks in question.

Someone's been "Bad."

Police are looking for the person who moonwalked off with a pair of signed Michael Jackson shoes - and the certificate of authenticity that went with them - from an auction at the Loews Hotel early this morning.

According to city police, who responded to the hotel at Market and 12th streets around 2 a.m., hotel security was watching the room with the shoes in it when security officers left to handle an unknown incident at the other end of the hallway.

When the guards returned, the King of Pop's signed kicks were gone, along with the certificate of authenticity that went with them, police said.

Security scoured the hotel, but came up empty handed, police said.

Authorities did not divulge the name or nature of the auction, but they did say there were about 2,000 people in attendance.

According to its website, the 19th annual Hair O' the Dog gala, which bills itself as "Philadelphia's swankiest black tie affair," was held at the hotel last night. A spokesperson for the event did not immediately return a call for comment and a manager at the hotel said he was not allowed to comment on the theft.
