An off-duty narcotics officer has been arrested for shooting two friends while the three drunkenly gallivanted on Amsterdam Avenue last night. Victor Zambrano Jr., 49, allegedly gave his weapon to a 31-year-old woman when she asked to hold it on West 82nd Street and Amsterdam Avenue around 9 p.m. Friday. Zambrano, a New York State Bureau of Narcotics enforcement agent, got into a tug of war with the woman when she wouldn't give it back, and bullets started flying. "We do not know if he was shooting at them or just shooting," a police source told the News. "Everyone involved is really drunk."

Zambrano allegedly shot the woman in the left foot and the woman’s 42-year-old boyfriend in the right calf. The boyfriend then chased after Zambrano up Amsterdam; plainclothes cops arrived and surrounded Zambrano outside Bustan on Amsterdam Avenue near W. 84th Street.

A tense standoff followed for a few minutes when Zambrano refused to give up the gun. "They were shouting ‘Drop the gun! Drop the gun!’ but he wouldn’t," a witness told the News. "A cop knocked it down and wrestled him the ground."

Both victims were taken to St. Luke's Roosevelt Hospital in stable condition. Zambrano has been charged with criminal possession of a weapon, resisting arrest, and two counts of assault. "He got drunk and did something stupid," the News says his son Vic Zambrano III, 22, said as he entered the 20th Precinct, where his father was being held. "It just escalated. It could easily have been prevented."
