Santa Cruz police are seeking a man who allegedly robbed a Walgreens store Friday night and then eluded authorities after a high-speed chase into Monterey County. The robbery was reported shortly before 9:55 p.m. Friday at the store located at 1718 Soquel Ave., according to police. The suspect entered the store and allegedly simulated having a firearm under his sweatshirt while demanding cash, police said. He then jumped over the cashier’s counter and took out a knife because the cashier was not carrying out his demand fast enough, according to police. The suspect left the store with cash and was seen riding east on Soquel Avenue on an orange late-model Kawasaki motorcycle, police said. No one was injured during the robbery.About 10 minutes later, CHP officials spotted the suspect and motorcycle near Portola Drive and 26th Avenue in unincorporated Santa Cruz County, and Capitola police spotted him in their city in the area of Brommer Street and 30th Avenue. Authorities chased the suspect from Capitola into Santa Cruz, and then south through Watsonville onto state Highway 1, state Highway 129, and then U.S. Highway 101, police said. The suspect was able to lose the pursuing officers in the Echo Canyon area of Monterey County after reaching speeds of up to 120 mph on the highways and 70 mph on surface streets, according to police. The suspect is described as a white man in his mid 20s who is about 5 feet 11 inches tall with a thin build and light complexion. He was last seen wearing a black hooded sweatshirt, low-slung jeans, a black motorcycle helmet with a design on the side, and a black motorcycle jacket with silver writing on it, police said. CHP officers, Capitola police, and Santa Cruz County sheriff’s deputies assisted during the pursuit. Anyone with information about the case is urged to contact the investigations section of the Santa Cruz Police Department at (831) 420-5820.
