Karachi: A heavy contingent of police have reached  Pakistan Tehreek-e-Insaf Chairman Imran Khan's Zaman Park residence to arrest the former Prime Minister of the country.

The official Twitter handle of the party urged its supporters to reach Zaman Park.

He is reportedly facing arrest in the Toshakhana case.

It is the only case against the former PM where his arrest warrant has not been suspended.

On Monday, a district and sessions court in Islamabad restored the former prime minister's non-bailable arrest warrant in the Toshakhana case. The Islamabad court had earlier reserved its verdict on a petition filed by him seeking an exemption from the hearing, reports Geo News.
