MANCHESTER -- Police are seeking a 6-foot-tall, 200 pound man who pointed a handgun at a clerk during the daytime robbery of a convenience store.

The robber entered SMA Market, 326 Maple St., about 9:50 a.m. Tuesday with his gun at the ready.

Police said the robber demanded more than the $20 bill that the 52-year-old clerk gave him. He ordered the clerk to lie face down on the floor, took more cash from the register and fled, running west on Cedar Street and then cutting north between two buildings.

The robber was wearing a hooded sweatshirt that is either black or grey. He wore long, dark pants and black gloves and what appeared to be a watch on his right wrist. Police said the handgun was a black semiautomatic.

Anyone with information about the robbery should contact Manchester police at 668-8711.
