CARY, N.C. — Raleigh and Cary police are looking at a possible link between two convenience store robberies that happened in the early morning hours Tuesday.

Shortly after 1 a.m., Raleigh police said a man entered the Kangaroo Station store at 6317 Creedmoor Road with what appeared to a gun under a blue towel that was draped over his right hand.

Police say the man walked behind the counter, demanded that the clerk open the cash register and took money from the cash drawer. He then left the store, where he was last seen running east on Lynn Road.

The man is described as a black male with a mustache and medium complexion in his late 20s to early 30s, standing about 6 feet tall and weighing about 180 pounds. He was wearing a red baseball cap, white T-shirt, blue shorts and white Nike shoes.

Cary police are investigating a convenience store robbery that happened just before 5 a.m.. Authorities say a man entered the Kangaroo Station at 1001 SE Cary Parkway and demanded money from the store's clerk and left on foot.

That man is described as a black male with a mustache, standing about 6 feet tall. He was wearing a white T-shirt and blue shorts and was carrying a blue towel over his shoulder, police said.

Police ask anyone with information on either of the robberies to contact local authorities.
