Panaji, Feb 25 (IANS) Anti narcotics sleuths are tracking down the Kazakh girlfriend of an alleged Israeli drug peddler arrested in the coastal belt of north Goa for possesing durgs worth Rs 3.81 lakh.

The residence of David Graham alias Dudu was being searched for nearly 48 hours for documents related to his import export company, which police suspect was used to transport drugs out of India, a senior police official said Wednesday.

"Yes... his girlfriend is missing. We had summoned her to the anti narcotics cell police station, but she has suddenly disappeared," Superintendent of Police (ANC) Veenu Bansal told IANS.

Bansal however refused to reveal the identity of the Kazakhstan national.

Dudu Division Import and Export Pvt Ltd, a firm run by the accused, came under the police scanner after its annual returns showed profits only once in 2005.

The company specialises in exporting chocolates and garments.

"We are interested in knowing the exact nature of their business. The company has the making of a front for drugs," the official said.

Dudu was arrested Monday at Anjuna and 144 ecstasy tablets as well as quantities of heroin, cocaine, liquid LSD and charas were seized from him.

Bansal added that Dudu had been earlier arrested in 2008 by the Mumbai anti-narcotics squad. He was also arrested in 2006 for over staying.
