After an explosive press conference regarding allegations of poll rigging, the outgoing Rawalpindi commissioner surrendered himself to the police, who arrested him and sealed his office.

A local official said the office was sealed since the administration wanted to prevent record tampering.

However, a police spokesman said the commissioner was not arrested as there were no cases against him, but he was in “custody” after the allegations.

Chattha has been shifted to some unknown place.

A senior district administration official said security of the polling staff, returning and district returning officers had been increased and election material and data had been secured.

He said though election results were already provided to the ECP, the official record with ROs has also been protected.
