A Summerville man is in custody after a massive police search for two bank robbers Friday afternoon prompted a two-hour lockdown at a half-dozen North Charleston schools, authorities said.

Six schools went on administrative lockdown after the Bank of America at 5900 Core Drive was robbed around 1 p.m. The "code yellow" lockdown for the schools in the East Montague Avenue area was lifted around 3:30 p.m.

At 9:30 p.m. Friday, North Charleston police arrested Brett Alan Brown, 38, of Ballantine Drive, Summerville, at the Relax Inn Hotel on Ashley Phosphate Road on suspicion of bank robbery. It was not immediately known what part he played or if police were still searching for a second suspect.

Earlier Friday, police said a man went inside the Bank of America and demanded money from a teller, according to North Charleston Police Department spokesman Spencer Pryor.

The teller gave the man an undetermined amount of cash. The robber ran then outside and got into a red vehicle, Pryor said. The vehicle had several bumper stickers on the back and was being driven by a black man, he said.

Police officers later found the car abandoned about three miles away on Marson Street. They determined that two men then escaped in a gray vehicle, but a precise description of the car wasn't immediately available, Pryor said.

The search for the robbers prompted a heavy police presence along Interstate 526. Marson Street parallels the highway for a short distance near the Rivers Avenue interchange.

Brown's bond hearing was expected to take place Saturday, the police statement said.

The six schools that had been under lockdown were: Hursey Elementary, Morningside Middle, Liberty Hill Academy, North Charleston Creative Arts Elementary, Charleston County School of the Arts and Academic Magnet High.

"The kids are safe," he said during the lockdown. "Everything is going on normally."
