(CNN) A man surrendered peacefully after barricading himself inside a Colorado police headquarters -- armed with a knife and a gun, authorities said.

The incident started Friday night when he walked into the lobby of the Arvada Police Department and made suicidal comments, authorities said.

A negotiator and a SWAT team arrived at the scene and worked to coax him out of the building, said police spokeswoman Jill McGranahan. Authorities used flash bangs to startle him so they could disarm him.

After he surrendered, he was taken to hospital.

The situation was contained to the police station and there was no risk to the surrounding communities, she said.
