WATCH: Suspects use sledgehammers in smash-and-grab robbery at California jewelry store

An eyewitness at the scene of the crime described how the intruders, wearing hoodies and face masks, entered the business and threatened the employees, forcing them to stand down as they rummaged through the store's goods.

One of the armed robbers brandished a firearm as the accomplices continued to rob the establishment, destroy the store's cases, and steal the merchandise.

"They yelled 'Get on the ground, get on the ground,' and then I heard glass smashing," said Cera Lafabe, an employee of one of the stores near Valliani Jewelers. "They had sledgehammers, they were breaking the glass. Watching the employees after the fact…they were really shaken up."

Shortly afterward, footage from a security camera captured the robbers leaving the store and making their getaway in two vehicles: a bright orange Dodge Charger and a silver Chevrolet. From the footage, police have described the intruders as a group of males between the ages of 16 and 22, KCRA 3 reported.

Police spokesperson Rob Baquera told CBS Sacramento that the charges facing these suspects could be wide-reaching. "There's a number of charges they could face," Baquera told the local outlet. "Organized retail crime theft is certainly one. They obviously worked in a coordinated fashion to hit this store."

Baquera told reporterss that the nature of the robbery was usual for Roseville and that the police force has deployed all available resources to detain the suspects.

"We're looking for the public’s help on any information available," Baquera said.

Local authorities are encouraging anyone with knowledge of the incident to reach out to the Roseville Police Department at 916-774-5000.
