A man wielding a “Star Trek Klingon-type sword” robbed two Colorado Springs convenience stores early this morning, police said.

The first robbery happened at about 1:55 a.m. at a 7-Eleven at 145 N. Spruce St., Colorado Springs police said in an incident report. The second robbery happened at about 2:20 a.m. at a 7-Eleven store at 2407 N. Union Blvd.

Witnesses told police that a man wearing a black mask, black jacket and blue jeans entered the stores carrying a sword. The armed robber took an undisclosed amount of cash and fled on foot from both stores, police said.

Officers searched the area but didn’t find the robber or the weapon, which was described as a “bat’leth.”
