The manager of Korean girl group Ladies' Code has been arrested for excessive speeding in the accident which cost singers Eunb and Rise their lives.

The stars were two of seven passengers in a vehicle which slammed into a Yeongdog Expressway guardrail en route to Seoul from Daegu in September (14).

Three survivors were injured in the accident and discharged from the hospital late last month (Oct14).

Police estimate the manager, identified only by his last name Park, was travelling at 84 miles per hour (135 kilometers per hour) - almost twice the local speed limit - when the accident occurred, according to Billboard.com.

Park previously testified he lost control of the vehicle after a rear wheel came off prior to the accident, but investigators have since concluded it flew off after impact, ruling there was no initial defect with the vehicle, as was previously claimed.
