Stagecoach has warned that if the vandalism continues, the S5 could be withdrawn from the area. A notice sent to the ward councillors at Oxfordshire County Council and Bicester Town Council from the bus company said: "Given the damage sustained, frequency of incidents and risk to our driver and passengers we have serious concerns about the safety of our vehicles operating along Sunderland Drive and in the Glory Farm area. "I regret to inform you that should these incidents continue then we will have no choice but to withdraw our S5 service from the area." Stagecoach says the incidents were reported to the police and CCTV from the vehicles was downloaded, but officers have been unable to pursue investigations as the incidents always happen at night when it it is dark.
