Three Gorham schools locked their doors for about three hours Thursday as police executed a search warrant nearby, officials said.

Superintendent Heather Perry said the high school, middle school and Village Elementary were placed in “secure status” because of a police “situation in a nearby neighborhood.”

Secure status means all exterior doors are locked and no one is permitted to enter or exit the buildings. There was no active threat inside the schools.

Gorham police officials on the scene Thursday said they were assisting South Portland police as they executed a “high-risk” search and arrest warrant at 20 Preble St., where one person was arrested. Police left the scene around 2 p.m.

The “secure status” ended around 1:30 p.m., according to a message sent to families.

Gorham police issued a ‘Code Red’ warning to residents within a half-mile radius of the location “out of an abundance of caution,” South Portland spokesperson Shara Dee said, and also notified the nearby schools.

A message sent to families from the Village School earlier Thursday described the move as “a precautionary step to keep everyone safe.”

“We will remain in secure status until the police notify us that it is safe to lift it. Please know that your student is safe,” the message said. “There is no need for any student to be dismissed, and in fact, it is safer for students to remain inside the school at this time.”

Adam Figueroa-Gomez, 19, of Gorham, was arrested at 20 Preble St., Dee said in a statement Thursday night. He is accused of shooting into a crowd in Redbank Village in South Portland on Sept. 23. No one was injured.

Figueroa-Gomez is the second suspect arrested in connection with the Sept. 23 incident. Several people called 911 that night, reporting shots were fired into a crowd from a vehicle in the area of the Redbank Community Center parking lot, Dee said. The vehicle fled, Dee said, but evidence was recovered from the scene confirming the reports of gunfire.

Following interviews with witnesses, detectives zeroed in on two suspects and the vehicle believed to be involved, Dee said.

The first suspect, Zane Ibrahim, 18, of Kennebunk, was arrested Sept. 24, Dee said.

The Sept. 23 incident was preceded by a similar one on Sept. 20, when 911 callers had reported gunshots in the area of Westbrook Street and Devereaux Circle in South Portland, Dee said.

No injuries were reported in either incident, Dee said.

Figueroa-Gomez and Ibrahim have been charged with criminal threatening, reckless conduct and terrorizing. Figueroa-Gomez faces an additional charge for violating conditions of release.

Thursday marked the second time in a month that the three schools in Gorham were placed in secure status during a police response in a nearby neighborhood. The schools briefly locked down on Sept. 2 as police conducted another “high-risk” search at a home on Narragansett Street.
