Two men wanted in connection with the attempted stabbing of a convenience store clerk in Sandy have been arrested, and investigators Friday were looking for a third.

About 4:50 a.m. Sunday, three men pulled up in an SUV to a Maverik Country Store, 425 W. 9000 South. Two men dressed in red got out of the car and entered the store. One went straight to the beer cooler while the other asked the clerk for cigarettes, said Sandy police Sgt. Victor Quezada.

After the clerk grabbed a carton of cigarettes, the would-be robber demanded money and displayed a knife, Quezada said. Without being provoked, the man lunged at the clerk, he said.

The clerk was able to make a quick move and grab his attacker's arm without being cut, slide past him and run out the door, Quezada said. The robber, in a move investigators said was unusual, chased the clerk out the door while still holding the knife. The convenience store worker was able to get away.

After surveillance video of the incident was broadcasted by the media, investigators received several tips pointing to the same people, Quezada said.

A 17-year-old boy was arrested at his home Wednesday without incident. A second person, a 19-year-old man, was arrested in similar fashion Thursday.

The third person being sought in connection with the incident has been identified as Johnathan Anderson, 18, of Midvale. Police describe Anderson as 5 feet 11 inches tall, weighing about 140 pounds and having red hair. He is wanted on a $100,000 warrant.

Investigators were also looking at possible gang ties with the trio.
