LAHORE: The Pakistan Muslim League - Nawaz (PML-N) on Wednesday suspended the party membership of a female provincial lawmaker over a recent altercation with the hostess of a local bus service.

A passenger bus of a local company was on its way from Murree to Lahore when PML-N MPA Nighat Sheikh allegedly manhandled the hostess of the bus service following a quarrel with her on Motorway II at Bhera Terminal on Sunday.

The PML-N, which is the ruling party in the National Assembly, also issued a show-cause notice, seeking a reply from the provincial lawmaker over the incident.

Taking notice of the incident Punjab's Chief Minister Shahbaz Sharif had directed the IGP to conduct an impartial inquiry into the incident.

Initially the Bhera police in an attempt to appease the ruling party’s woman legislator quickly registered a case against the hostess, but later the case against her was discharged and the police was directed to submit a report after conducting investigation on merit, on the instructions of the chief minister.

Nighat was nominated as an MPA on a reserved seat for women after the recently held General elections of 2013.
