Prior to Pathak's arrest, two managers of "1 Above" pub Kevin Bawa and Lisbon Lopez were also arrested in connection with the fire tragedy.
Acting on a tip-off, Mumbai police arrested two owners Jigar Sanghvi and Kripesh Sanghvi late on Wednesday night while Abhijeet Mankar, who was on the run, was arrested on Thursday morning.
This was added to the previous FIR accusing the owners of 1Above and Mojo's Bistro for culpable homicide not amounting to murder.
Following the Fire Brigade report, the police last week arrested Yug Pathak, one of the co-owners of Mojo's Bistro.
After the Sanghvi brothers' arrest, sources said police acted on inputs shared by Vishal Karia.
The police then laid a trap to nab the brothers when they came to an eatery to meet a senior lawyer in Bandra.
Kripesh and Jigar are likely to be presented in court today, while the third partner Abhijit Mankar is still missing. They were crossing the road in Badra, when the Police, which had been positioned their, spotted them, gave chase and apprehended the brothers. "Karia said that the moment the accused saw that the FIR named only them and not the Mojo's Bistro owners, they left without disclosing their location", said an officer. They will be produced before a court on Thursday, The Times of India reported.
They were tracked with the active mobile numbers, revealed by Juhu hotelier Vishal Karia during police questioning. The police has also stated that the two could have valid information about the location of Mankar. Karia is also likely to be interrogated to find out if he provided financial assistance to the Sanghvi brothers and his Audi auto has also been seized.
