Former Pakistani Prime Minister Imran Khan was shot in the leg at a protest rally in the eastern city of Wazirabad.
A senior official told AFP that the incident was an “attempt to kill” Khan, but police have yet to confirm that he was the target.
Members of his party, the Justice Movement, said four other people were wounded in the shooting.
Khan, 70, was leading a rally in the capital, Islamabad, to demand early elections after he was ousted in April.
The former prime minister was seen being taken to a hospital in Lahore. A party spokesman said he was shot in the leg.
Yasmin Rashid, a party leader and provincial health minister, said Khan was in stable condition.
The authorities later arrested a suspected man, according to Pakistan’s Geo TV.
Footage was released showing Imran Khan being transported in a car after the shooting. He was conscious, and there is a bandage on his leg.
Videos circulating on social media show a party member, bandaged and dressed in blood, saying that people should pray for Khan and all those injured.
The current Prime Minister, Shahbaz Sharif, condemned the shooting incident and ordered an immediate investigation.
Khan is leading a protest march, which has been going on for 7 days, to demand new elections. This is the second march of its kind this year.
The government has repeatedly said it will hold elections next year as planned.
Last month, the Election Commission of Pakistan disqualified Khan from holding public office in what the former cricket star called a politically motivated decision.
Khan is accused of inaccurately publicizing the details of gifts from foreign dignitaries and alleged proceeds from their sale. Gifts included Rolex watches, a ring and a pair of cufflinks.
