SEATTLE – Seattle Police officers arrested a burglar at a Capitol Hill school early Wednesday after the man barricaded himself inside a basement room and booby-trapped it with vegetable oil.

Around 2 AM, police got a call saying someone had broken into an administrative building. Officers arrived and spotted the suspect through a window, surrounded the building and called for a K9 team to search inside.

In the basement, K9 Pele began barking at a door.

Officers opened it to find a barricade of boxes inside. As Pele continued to bark, officers kicked aside the boxes and discovered a sheen of vegetable oil, which the suspect had apparently dumped all over the floor of the room.

The suspect eventually came out of hiding and surrendered.

Officers recovered a bag of change and some computer parts he’d taken from the school and booked the 24-year-old man into the King County Jail for burglary.
