WALLINGFORD — A Waterbury man charged last month in a string of Southington robberies faces additional charges after police said he robbed a gas station on South Colony Road at knifepoint in January.

Jeffrey Stokarski, 43, was charged by warrant Friday with first-degree robbery, third-degree larceny, and third-degree assault. 

On Jan. 6 around 11:25 p.m. police responded to the Food Land Gas and Convenience Store, 250 S. Colony Road (Route 5), for an alarm.

Police met the store clerk on Ward Street. The clerk said he chased, but lost sight of the suspect, later identified as Stokarski, according to Stokarski’s arrest warrant.

The clerk told police Stokarski entered the store, placed drinks on the counter and asked to look at an item in a glass case, the warrant said. While the clerk was unlocking the case, Stokarski placed him in a headlock. Stokarski then pulled out a knife and put it to the clerk’s side and dragged him toward the front counter.

Stokarski rummaged through the drawers while struggling and holding the clerk, then slammed the clerk’s head against the counter, the warrant said. Stokarski threw the clerk to the ground, then took cash and cigarettes and fled.

Police viewed store security video and recognized Stokarski from a notice released by Southington police on similar robberies, the warrant said. On Feb. 19, Southington police charged Stokarski in four robberies that occurred in December and January on Meriden-Waterbury Turnpike.

Stokarski was arraigned in Meriden Superior Court on Friday. The judge set bond at $150,000 and transferred the case to New Haven Superior Court, where Stokarski is scheduled to appear on April 10.
