Police say 53-year-old James Lacroix told them he was "looking for Katy Perry" at the the Kennedy compound.

(CNN) -- A man wearing a Captain America T-shirt and camouflage shorts broke into the Kennedy compound in Barnstable, Massachusetts, on Tuesday, police said. When officers asked him what he was doing there, he replied: "Looking for Katy Perry."

Officers went to the house in the village of Hyannis Port after receiving a call from Ted Kennedy Jr., who said he had phoned the property from his home in Connecticut to check on his teenage son and a stranger answered.

Police found a black car parked outside the home. Inside the home, they found 53-year-old James Lacroix in the kitchen, said police Officer John O'Hare. The teen was also in the kitchen; he was unharmed.

Lacroix told police he had been there for three hours and was looking for Perry, the pop singer.

He was booked on breaking and entering charges and and will be arraigned in Barnstable District Court on Wednesday morning.
