Former Pakistan cricket captain Wasim Akram's car has been fired at in Karachi, the country's commercial capital, police say.
The shooting took place near the National Stadium in Karachi's Karsaz area on Wednesday, reports said. The ex-bowler was not hurt in the attack.
Police said the incident appeared to be a case of road rage.
Gun violence is not uncommon in Karachi, with much of it linked to militant groups.
Wasim told the Express News channel: "A car hit mine, I stopped him and then his guy stepped out and fired at my car."
Police say a hunt is on to arrest the owners of the other car, the BBC's Pakistan correspondent Shahzeb Jillani reports.
The cricket legend, who retired in 2003, is massively popular in Pakistan.
The great left-arm paceman took 502 one-day wickets and claimed 414 Test victims in a 19-year international career.
He is currently taking part in a training camp in Karachi, coaching young bowlers from across the country.
Many in Pakistan, including politician and former cricketer Imran Khan, were quick to condemn the attack and express relief that Wasim was unhurt.
