Police will seek Interpol’s help to ascertain alleged Pakistani links of the hawala transaction racket busted by Lakhisarai police with the arrest of four persons on Saturday.

A key accused in the racket and alleged fund mobiliser for the Indian Mujahideen — Ayesha Bano — and her husband Md Jubair were arrested from Mangalore in Karnataka on Tuesday. The couple is being brought to Lakhisarai by train on transit remand.

Director general of police (DGP) Abhayanand said: We have decided to seek the Interpol’s help to ascertain the involvement of some Pakistani nationals in hawala transactions. Their involvement has been established on the basis of calls made from Pakistan to their Lakhisarai-based agents,” he told The Telegraph.

Sources said at least 39 calls were made from Pakistan on the cellphone of one of the four persons arrested in Lakhisarai. The agents were in touch with Ayesha and some Pakistani nationals, who deposited money in their bank accounts. The money was subtransferred through real time gross settlement (RTGS).
