The owner of Heist Jewelry in Santa Monica was hit with a sledgehammer while thwarting a robbery at his store Thursday, officials said.
The robbery occurred about 2:35 p.m. at the store along the 1200 block of Montana Avenue, according to the Santa Monica Police Department.

The owner intervened and was able to push the suspect out of the store, police said. A second suspect, also carrying a sledgehammer, approached the owner and hit him with the weapon.
During the struggle, the owner managed to take the suspect's sweater off, who then tried to conceal his face, surveillance video from inside the store showed.
The two suspects were able to get away in an awaiting car, police said.
