New York City police were holding a suspect Saturday who theysay tried to turn in a live hand grenade to police at a gun-buybackprogram in the Bronx.

Authorities say the NYPD's bomb squad responded to a churchwhere guns were being collected at around 4:30 p.m. and left 15minutes later with the grenade, carrying it out in a specialcarrier. The program, which offers $200 for guns - no questionsasked - had started Saturday across the Bronx.
