(KRON) -- Broadmoor police are warning residents of a rash of late-night vehicle break-ins and vandalism. Six vehicles have been impacted by thefts of valuables inside the vehicles and vandalism between Sunday and Wednesday, according to the Broadmoor Police Department. Vehicles parked in a residential area near the South Park Plaza Drive and 87th Street intersection have had wallets, cash and other items stolen, authorities said. The common theme in the thefts, according to police, is that the majority of vehicles were left unlocked. The break-ins have occurred between 10 p.m. and 2 a.m. overnight. Police did not tell KRON4 the number of suspects that may be involved. However, they do believe all the incidents are connected. No arrests have been made as of Thursday night. Broadmoor PD said the thefts have occurred within its jurisdiction, though the vehicles parked on S Park Plaza Dr. are Daly City residents. The Daly City Police Department was notified of the incidents.
