Pakistani police and supporters of Imran Khan fought pitched battles on Tuesday outside the former prime minister's home in the eastern city of Lahore, injuring several on both sides, ahead of his possible arrest, a government spokesman and witnesses said, Reuters reported.

A few hundred Khan supporters gathered outside his house after a police team arrived from Islamabad to arrest him on a court order, government spokesman Amir Mir told Reuters.

Khan's Pakistan Tehreek-e-Insaf (PTI) workers started the violence, which injured several police officials, Mir said.

Similar clashes took places last week, too.

The workers started pelting the police with stones and bricks, and in response police directed a water cannon at them and in some cases baton charged them, deputy inspector general of police Syed Shahzad Nadeem told reporters.

The court in Islamabad had issued the arrest warrant in a case against Khan for unlawfully selling state gifts while in power from 2018 to 2022.

The former premier has been embroiled in several court cases since his ousting early last year in a parliament vote of confidence.

He has been demanding snap polls in protest rallies across the country, a move his successor Shehbaz Sharif has rejected, saying the elections would be held as scheduled later this year.

Khan was also shot and wounded in one of these rallies.
