A joint team of the police and the special task force (STF) arrested a man, suspected to be a shooter, from Mumbai on Wednesday in connection with the murder of Vishwa Hindu Mahasabha leader Ranjit Bachchan.

Sources, privy to the investigations, said the Mumbai connection emerged after call details of Bachchan's relatives were scrutinised, following which a team nabbed the shooter on Wednesday. As per these sources, the accused had allegedly gone into hiding in Mumbai after the incident.

After the shooter was arrested, two other persons were also taken into custody from neighbouring areas, police sources said, and added that the joint team will reach Lucknow on Thursday.

The Lucknow police had earlier on Wednesday detained four persons in connection with the murder of the right wing Hindu outfit leader, who was shot dead while he was out on a morning walk in Hazratganj.

The four were detained by the Special Task Force of the Lucknow police from Gorakhpur and Raebareli.

Ranjeet Bachchan, 40, who had founded the Vishwa Hindu Mahasabha, was shot in the head and his cousin Aditya Srivastava injured in the attack by an unidentified assailant who also snatched their mobile phones.

The attacker had covered himself in a shawl and was on foot, police had said quoting eyewitnesses.

Four police personnel, including a sub-inspector, were suspended for alleged laxity and a case has been registered at Hazratganj police station here in connection with the incident which occurred near the Collectorate building.

Later, police released CCTV footage showing a suspect and announced a cash reward of Rs 50,000 for providing information.
