Two suspects, known as the "Grinch Bandits," are believed to be responsible for at least seven armed robberies throughout San Diego County, according to the San Diego Police Department.
Lt. Eric Hays, who oversees the robbery unit at SDPD, told NBC 7 the store that has been hit the worst is Godfather's Pizza in Spring Valley.
"It has been targeted three times," Hays said.
SDPD believes the Grinch Bandits are also responsible for other robberies that occurred at KT Donuts in Spring Valley, a 7-Eleven in Sabre Springs, B Beauty Supply & Wig in Spring Valley, and a Valero gas station in Serra Mesa.
National City Police also brought forward a case from Dec. 3, where suspects with similar descriptions targeted Oriental Cafe on E 7th Street.
Detectives are looking at the descriptions and matching evidence to each case, according to Lt. Hays.
Investigating officer Lt. Graham Young, with National City police, said there has only been one armed robbery in National City, and it was the Oriental Cafe incident.
"To our knowledge, this has been the only recent armed robbery in the area," Young said.
The suspects are described as traveling in a pair and wearing dark clothing when they target stores.
