Investigations into the murder of RTI activist and green crusader Amit Jethwa has led the police to Shiva Solanki,the nephew of BJP MP from Junagadh Dinu Solanki.
Crime Branch officials said they are probing the role of Shiva Solanki in the case and a team has left for Junagadh to question him.
Sources in the Crime Branch alleged that Shiva could be the one who paid for the murder of Jethwa.
Two people,including a police constable from Junagadh,have been arrested in connection with the crime. Jethwa had filed a public interest litigation (PIL) against illegal mining in the Gir forest region,a few days before he was shot dead.
A day after his murder on July 20,his father Bhikabhai Jethwa had alleged that Dinu Solanki was behind the crime.
On Monday,the Crime Branch arrested police constable Bahadursinh Dhirubha Wadher,37,posted in the Girgadhada police station in Junagadh district,in connection with the murder of the activist.
Another accused Pachan Shiva,28,one of the two motorcycle-borne assailants,who had allegedly shot Jethwa,was arrested on Wednesday.
Crime Branch officials confirmed that the name of Shiva Solanki surfaced during the interrogation of Wadher and Pachan.
According to the police,Wadher had given the contract to kill Jethwa to Shiva and one Shailesh Pandya,a sharp-shooter,who is still absconding.
Both Shiva and Pandya had come on a motorcycle and allegedly shot Jethwa from a close range outside the office of his lawyer near the Gujarat High Court on July 20.
The police said Wadher had promised both Shiva and Pandya Rs 11 lakh for the murder.
Shiva Solanki,who is Kodinar municipality vice president; has not been seen in his town for the last one week. He might be arrested anytime,Crime Branch officials said.
The PIL filed by Jethwa in the Gujarat High Court mentions Dinu Solanki and Pratap Solanki as respondents. In the petition,he alleged the uncle-nephew duo were involved in illegal mining in the Gir forest.
