SAN FRANCISCO (CBS SF) - A hand grenade found by a man with a metal detector shut down a portion of San Francisco's Golden Gate Park for more than two hours Thursday afternoon, police said.
The discovery was reported at about 1:10 p.m. in the 1300 block of Martin Luther King Jr. Drive, near Mallard Lake, after the metal detector revealed the grenade's presence, police said.
Officers shut down the area to traffic and the department's bomb squad responded. They rendered the grenade safe at about 3:30 p.m., police spokesman Sgt. Mike Andraychak said.
Traffic was reopened in the park about five minutes later, he said.
No one was injured in the incident.
