SAN MARINO — Police investigating a break-in at a Mesa Road home discovered three grenades Thursday, which were ultimately found to be inert training grenades.
A gardener called police around 3 p.m. to report a window had been smashed at a home in the 1200 block of Mesa Road sometime since his last visit to the home on Tuesday, San Marino police Sgt. Robert Cervantes said. The residents were out of town.
Investigating officers found that the home had been ransacked and noticed three grenades sitting on a bed in the master bedroom.
“We cleared out of there, just to be on the safe side,” the sergeant said. A bomb squad was summoned, but cancelled before arriving after a police officers recognized the grenades as harmless training devices.
Officials left the devices, which are note illegal, at the home but dismantled them to avoid further misunderstanding, Cervantes said.
It was not immediately clear what, if anything, was taken from the home.
The investigation into the burglary was ongoing.
