THE WOODLANDS, Texas -

A man pepper-sprayed employees of a high-end jewelry store on Wednesday, detectives said.

Investigators said a man armed with a gun walked into the Tiffany & Co. at Market Street in The Woodlands about 4:20 p.m. and sprayed everyone inside.

Paramedics were sent to the store to treat those affected. Officials have not said how many people were sprayed.

Sources told KPRC Local 2 that the man didn't get away with any merchandise.

Shoppers and employees at some nearby stores said they were placed on lockdown while investigators search for the man. Detectives said he may have had a getaway driver.
