MARIETTA, Ga. — A man who claimed to have a bomb that could “take out the room” barricaded himself inside a suburban Atlanta bank Friday, sparking an hourslong standoff that forced police to bust through a brick wall of the building and later ended with the suspect’s death.

Cobb County police Chief Mike Register did not offer details Friday of how the man died. Two people were freed shortly after TV footage showed a military-type vehicle smashing its way through the wall, raining bricks onto its hood. However, it’s not clear if they escaped through the wall opening.

Several heavily armed police officers had converged on the bank earlier in the day.

Police had said the man inside the bank branch near Marietta had made threats and was inside with an unknown number of employees.

Police had previously limited the amount of information they made public, saying the suspect might be monitoring news coverage and social media, Cobb County police Officer Alicia Chilton said in a statement.

WSB-TV in Atlanta reported the station received a call Friday morning from a man said he was inside the bank and talked for more than 30 minutes.

The man told the station’s assignment desk that he had a bomb and two people with him.

The man said he didn’t intend to hurt anyone, the station reported. He also said he was a homeless Marine Corps veteran who had served in Iraq and that he was unhappy with the U.S. Department of Veterans Affairs, which provides health care to veterans. The man’s identity had not been released and his claims could not immediately be verified.

In the station’s video account of the conversation, the man can be heard saying that the bomb had the power to “take out the room.”
