The Pakistani police entered the property of former prime minister Imran Khan in Lahore, officials from his political party said, as he appeared in court in Islamabad.
The move followed days of standoff and clashes between police and supporters around the property, where police tried to arrest Khan on Tuesday.
Khan was facing charges in the Islamabad court of unlawfully selling state gifts given to him by foreign dignitaries while he was in office.
Hours earlier in his home in Lahore, the former cricketer told a committee that he had formed a committee to lead his party if he was arrested.
He has lead nationwide protests after he was ousted from power last year and a number of cases have been registered against him.
Khan, who was shot and wounded in November, said in an interview that the threat to his life was larger than before and added without providing evidence that his political opponents and military want to block him from standing in elections later this year.
The military and government did not respond to requests for comment.
Security was tight around the judicial complex where Khan, 70, arrived in a motorcade surrounded by supporters.
The court had previously issued arrest warrants for Khan in the case, because he had failed to appear on previous hearings despite summons.
