Colton police are searching for a man who stabbed a Colton store clerk in the upper body and head during a robbery, officials said Wednesday.

A man who allegedly attacked a store clerk in Colton on Nov. 14, 2017 is seen in surveillance video released by the Colton PolIce Department.
The incident occurred about 9:45 a.m. Tuesday at a smoke shop in the 1600 block of East Washington Street. The man walked into the store and demanded money, police said. A struggle ensued and the man stabbed the victim four times before running from the area, police said.
The victim was taken to a hospital in critical condition.
Authorities responded and searched for the man, but he was not found.
He was described as being in his late 20s or earl 30s, wearing a gray sweatshirt, orange shorts, black socks and white shoes, police said.
Anyone with information about the incident can call 909-370-5021 or 909-370-5000.
The clerk's wife told KTLA that her husband called her from the ambulance and told her what happened. She hopes someone will come forward and turn the man in.
"Someone should speak up because he's a dangerous man and this could happen to anyone," she said.
