A man arrested by Southington police Friday for a robbery there was arrested by police in Wolcott for crimes in that town as well.
Police said it was a sock that led them to the suspect.
Brett Downs, 32, was arrested in connection with robberies at the Cumberland Farms at 1655 Meriden Rd., police said.
Investigators said Downs entered the store on Dec. 23 with a knife, leapt over the counter, held the knife to a clerk's throat and demanded cash.
Downs allegedly cleaned out the register and fled.
A second robbery took place during the early morning hours of Jan. 31. Police said Downs again entered the store, held the knife to the employee's throat and emptied the register.
Detectives said they were able to link Downs to the crimes through DNA from a sock that he was wearing on his hand. The sock was left at the scene.
Downs was arrested by Southington police for a similar robbery. They said he's also a suspect in other robberies as well.
He was arrested while he was at a court appearance Tuesday.
Wolcott police charged him with two counts of first-degree robbery and two counts of sixth-degree larceny.
Police said he's being held on $600,000 bond.
