Mumbai/IBNS: The Mumbai Police has questioned a woman in West Bengal for allegedly providing a mobile phone SIM card to the accused Bangladeshi national who had entered the country illegally, and has been arrested for attacking actor Saif Ali Khan during a burglary attempt.

According to reports, the woman-Khukumoni Sheikh is from Chapra in Nadia district and was allegedly known to the accused Bangladeshi national, Sariful Islam.

"The SIM card the accused was using during his stay in India was traced to the woman. The woman is being questioned. She has, however, claimed that her phone was stolen earlier," NDTV reported quoting a source.

Police had earlier said that Sariful Islam entered India through Meghalaya seven months ago and stayed in Bengal for a few weeks, before moving to Mumbai in search of a job.

The cops who interrogated the accused said he crossed the Dawki river, along the India-Bangladesh border in Meghalaya, to illegally enter India, according to NDTV.

He then changed his name to Bijoy Das and began living in the country.

Saif was stabbed in five places including his back, wrist, neck, shoulder, and elbow, and was taken to Lilavati Hospital in Mumbai in an autorickshaw by his friend Afsar Zaidi, the actor's medical report stated.

The actor received a wound close to the spinal cord. Doctors had to perform surgery on him to remove the knife which was 2.5 inches deep into the wound.

The attack on the house of a top-level celebrity has left the Mumbai Police red-faced.

Islam earlier revealed that he wanted to steal money from someone rich and travel to his own country to treat his ailing mother.

The attacker had booked a train ticket from Mumbai to Howrah Station in Kolkata from where he had planned to travel to Bangladesh.

He has told police that someone had promised to get fake citizenship documents made for him in exchange for money.
