The black buck hunting case returned to haunt the Pataudi family with Haryana authorities deciding to issue a show cause notice to actress Soha Ali Khan for alleged Arms Act violations.

Soha and her father Mansur Ali Khan Pataudi, former cricket captain, faced trouble since he had allegedly used the gun issued in her name to kill an endangered black buck near Gurgaon for which he is facing a police case.

She was issued the gun license in November 1996, when she was only 18 years and one month old, whereas the minimum age limit for getting a gun license is 21 years, Gurgaon Deputy Commissioner Rakesh Gupta said on Tuesday.

She has been asked to explain in two weeks how she obtained a gun license when she was still underage and ineligible for it, Gupta said.

Gupta said if it is established that Pataudi had used the same weapon in hunting down a black buck, action would be taken against him and Soha on the charge of violating the Arms Act and misleading the Gurgaon administration.

Gupta also said the file containing documents related to the issuance of the license to her was also missing from government records and added that an FIR would be lodged against unnamed persons in this regard.

He said Pataudi took the permission for carrying .22 bore rifle no. 91501 "as retainer" on January 7, 2000 for which license was issued to Soha.

Pataudi had allegedly used the same weapon in June 2005 for hunting down and killing a black buck in Jhajjar district, the official said.
