Bharatiya Janata Party Babubhai Katara could be in a bigger soup as the police is now probing whether he was in possession of more passports allegedly used for trafficking people out of the country.

Besides, the police have sent teams to Gujarat and some other states to nab the travel agents who had been allegedly hobnobbing with Katara, who was arrested here while making an unsuccessful bid to smuggle a woman and a boy to Canada.

The Delhi Police was in touch with the FRRO to ascertain whether any other travel documents were issued in the name of 46-year-old Katara, a second-term parliamentarian from Dahod in Gujarat, or his family members.

They are also investigating his Hyderabad connections as it has come to light that the air tickets of Paramjeet and the teenaged boy were arranged by a travel agent from the southern metropolis.

Sources said police teams have been sent to Hyderabad, Hoshiarpur and to the parliamentarian's hometown of Jhalod in Dahod. A hunt is also on to nab the lawmaker's aide Rajendra Singh, believed to be brain behind the human smuggling racket.      

A special team went to his house and office in Jhalod and searched another house in his native village of Chitrodia but could not find his wife or son anywhere.

Investigators also collected details about his financial transactions from the Bank of Baroda's branch in Dahod to find out how much money he had received for smuggling people out of the country twice earlier.

Katara was arrested at the international airport in New Delhi on Wednesday when he tried to take Paramjeet and the boy on his wife and son's diplomatic passports.
