Siddiqui is the Pakistani bureau chief of Indian television channel WION and has reported for France 24.
In 2014 he won France's Albert Londres prize along with French reporters Julien Fouchet and Sylvain Lepetit for a documentary on healthworkers defying the Taliban to carry out a polio vaccination campaign.
He had complained of being harassed by the authorities for publishing criticising the country's security establishment.
The Rawalpindi-Islamabad Union of Journalists said it had contacted Interior Minister Ahsan Iqbal "to direct the concerned officials to investigate the incident of attempted kidnapping of a senior journalist".
Last year journalist Ahmed Noorani was beaten and stabbed in the head after being dragged out of his car by armed assailants in Islamabad.
Pakistan has a history of forced disappearances, linked partly to the US war on terror and partly to internal conflicts, particularly in Balochistan in the south-west of the country.
