PTI Chief Imran Khan has stepped out of his Zaman Park house wearing a gas mask.

Footage aired by Aaj News showed the former prime minister left the inner portion of his house at noon to meet hundreds of party workers who have gathered at Zaman Park to shield him from Rangers and police.

The party workers have successfully kept personnel of law enforcement agencies at bay since 2pm Tuesday.

Khan appreciated the courage of his supporters and told them to stand their ground, Saleem Sheikh reported.

This was the second time Khan stepped out since the siege began. Earlier, he came out at 7am on Wednesday.

The PTI chief refuses to surrender to police who want to arrest him in Toshakhana case. An Islamabad court issued a warrant for him after he failed to appear before it earlier this week.
