Two 21-year-olds are each facing charges of first degree trespassing after they allegedly roamed the halls of Interlake High School just before 2 a.m., on Aug. 31.

According to Bellevue Police, Derek Tsang and Aneesh Patel had driven the school they previously attended and were drinking alcohol in the parking lot before they decided to the enter the building and set off security alarms.

A school security officer said he saw the two subjects in the commons area of the school, and with the help of the Bellevue Police Department’s K-9 unit, and their dog Ghost, were able to track down Tsang inside the building and Patel, who was hiding in the back of the vehicle they had been drinking in, according to the police report.

Tsang told police he and Patel entered the building through an unlocked door after they had been “reminiscing about going there,” and “that they wanted to see the school they went to and walked around the building.”
