The Bommanahalli police arrested a 25-year-old Ola cab driver on Tuesday, for allegedly sexually assaulting a woman passenger on the night of April 28. 

Imran Khan, a native of Madhya Pradesh, who currently resides in BTM Layout, was arrested three days after the woman filed a police complaint, alleging that the driver had taken her to an isolated spot and molested her while she had hailed the cab to return home.

However, what delayed Imran's arrest was that he had been using the log in credentials of the previous driver. Ravikumar, the previous driver of the Ola cab, had quit his job in February. The owner of the cab Naveen Rajput, did not inform the cab aggregator about this and instead hired Imran Khan, and used the log in detail of Ravikumar to continue running the cab service. 

Police said after Navin and Imran learnt of the police complaint they went to the Ola office to erase the details of the former driver Ravikumar.

The police have booked Imran Khan on charges of molestation and impersonation, whereas Navin Rajput has been arrested for abetment, impersonation and destruction of evidence, said Hemanth Nimbalkar, additional commissioner of police (east).

According to a report by The Hindu, Imran Khan did not even have a valid driver's licence. A mobile phone and the car used has been seized, said police. 

The police are also investigating the possible involvement of Ola officials.
