Police arrested a 30-year-old man in India's financial capital Mumbai whom they said was considered the prime suspect in the stabbing of Bollywood star Saif Ali Khan.

Police in the central Indian state of Chhattisgarh on Saturday detained a second person suspected of involvement in a knife attack in which Bollywood actor Saif Ali Khan was wounded.

DCP Zone 9 said, "Prima facie the accused is a Bangladeshi and after entering India illegally he changed his name. He was using Vijay Das as his current name. He came to Mumbai 5-6 months ago. He stayed in Mumbai for a few days and then in the vicinity of Mumbai. The accused used to work in a housekeeping agency."
