Police are trying to negotiate with a man holed up in a home in New Jersey's capital city after they say he exchanged gunfire with police, killing a bystander person.

An official with the Mercer County Prosecutor’s Office said the shooting took place when the U.S. Marshals Service Joint Regional Fugitive Task Force attempted to serve a warrant at a home in the 300 block of Centre Street in Trenton around 6:30 a.m. Wednesday.

The officers reportedly entered the house and the suspect opened fire. Two Mercer County sheriff's officers were wounded, but their injuries were described as minor, the official said.

The victim has not yet been identified, and it is not clear whether the individual was shot inside or outside of the home.

As of 11 a.m., officers were still engaged in a standoff with at least one person.
