Pakistan Tehreek-e-Insaaf (PTI) Chairman Imran Khan on Tuesday called on his supporters to "come out" as party workers and police officials clashed outside his Zaman Park residence in Lahore, a Pakistani daily reported.

In a video message on Twitter, Imran said police had arrived to arrest him. "They think that after I am arrested, the nation will fall asleep. You have to prove them wrong."

"If something happens to me and I am sent to jail or if I am killed, you have to prove that you will struggle without Imran Khan and not accept the slavery of these thieves and of the one person who has been making decisions for the country," he was quoted by Dawn as saying.

PTI's Fawad Chaudhry also asked PTI supporters to gather in the streets in a peaceful protest in a show of solidarity with Imran.

Armored police vehicles had arrived outside Zaman Park with the intention of arresting Imran but a senior Islamabad police official, Deputy Inspector General (DIG) (Operations) Shahzad Bukhari, had refrained from commenting on the case in which officials were acting against the PTI chairman.

However, almost an hour later, police used a water cannon and tear gas against PTI supporters that had gathered outside Zaman Park in droves.

Footage broadcast on television showed police slowly inching toward the residence behind an armored vehicle that was dispersing PTI supporters with a water cannon. Supporters could also be seen pelting stones at the policemen, Dawn reported.

Footage also showed PTI supporters being teargassed as police arrived close to the main gate of Zaman Park. The workers, who had covered their faces with pieces of cloth and were carrying bottles of water, continued to pelt stones at officials. (KB/IANS)
