WATCH: Jewelry Store Smash & Grab

Miami-Dade police detectives are searching for four brazen smash and grab jewelry store robbers.

Surveillance video from the business in the 163rd Street Mall captured a man smashing the glass cases with a hammer while the others jumped the counter to grab the goods.

The store's owner, who was in the back, grabbed his gun and pointed it at the crooks.

They ran away with about $10,000 worth of jewelry.
