LPD detectives said they may be looking for the same two people in a pair of armed robberies.
Police said in both incidents a man threatened the clerk with a knife and had a woman accomplice.
A male and female suspect entered the Subway restaurant around 9 p.m. located at 50th and Slide armed with a knife. They demanded money from the register, however the clerk was unable to open the register.
The victim was told to turn and walk toward the rear of the store at which point the suspects ran out of the front of the store.
The first suspect is described as a Hispanic male, 5’10” wearing a red and gray shirt and baseball cap. The second suspect is described as white female, 5’6” with brown hair wearing a green hat and green jacket.
Ten minutes later, a male and female suspect entered the Dollar General at 908 Slide Road. They selected one item and then approached the counter. The male suspect then displayed a knife and demanded the cash in the register. The clerk complied and the suspects fled the scene with an undetermined amount of cash.
The first suspect is described as a Hispanic male with a mustache, wearing a red baseball cap, gray pullover and sweatpants. The second suspect is described as a white female wearing a red hat, sunglasses and a black shirt and black pants.
