Atlantic City police charged four people with obstructing justice this morning after a possible domestic situation led to a half-hour standoff.

Police passing by the apartment building on the corner of Baltic and N. South Carolina avenues at about 11:45 p.m. Tuesday heard a man screaming at someone and stopped to check on the welfare of the people inside.

The man went into an apartment, and refused to open the door. Several units arrived, including a K-9 team and members of SWAT. Shortly after midnight, two men and a woman came out of the apartment, and were taken into police custody and questioned.

The door to the apartment was slammed behind them and remained locked, with those left inside refusing to let officers in, police on the scene said. At least four children — including an 8-day-old baby — were still inside.

At 12:15 a.m., police gave one final warning, then broke down the door with a battering ram. Two other men were then led out in handcuffs.

Kenneth Crumble, Stephen Smith, Kenneth Sandoz and Hassan Buffaloe were charged with obstruction, Sgt. Monica McMenamin said. Smith also had an outstanding contempt warrant.

Police confirmed accounts of neighbors at the scene that a gun had been found in the residence about two weeks ago, which increased concerns as to the safety of those inside.
