Police surround the scene where a gunman barricaded himself with three children in Trenton, New Jersey.
A gunman who had barricaded himself and three children in a home in Trenton, New Jersey, on Friday was communicating with police, but the standoff continued into the morning, authorities said.
"We have state police on the scene, a SWAT team and a hostage negotiator present," said Lt. Mark Kieffer of the Trenton police department.
"We evacuated the surrounding blocks. And we're talking to him now."
The situation began in the afternoon, police said, but it was not immediately clear how it started or how old the children are, or their relationship to the man.
The standoff continued early Saturday morning, police said.
As of 5:30 a.m. negotiators were still talking to the suspect, but no hostages had been released, said Trenton Detective Lieutenant Steve Varn.
The ordeal had spanned more than 12 hours, police said.
