Shivam hospital's role surfaced in the beginning of police's investigation. Absconding accused Dr Manish Tripathi in his anticipatory bail application also claimed that Shivam hospital is the real culprit here. Dr Manish Tripathi runs a nursing coaching institute, KPEC, on the premises of Shivam hospital.

Mumbai Police in its investigation found out that Shivam hospital got vials from BMC before 30th April as the hospital had the vaccination permission only till April 2021 not beyond that.

As per Mumbai police, the hospital saved some of these vials. Some had vaccine in it and some were empty. And these vials were given by Shivam hospital to the accused who later administered these vials to Hiranandani housing society residents.

Before this, by Thursday afternoon, Bhoiwada police made two arrests. Accsued Seema and Shrikant allegedly helped Mahindra Pratap Singht to conduct an unauthorised vaccination camp at Poddar Education Institute where 207 people were given the jab on 28th and 29th May.
The scam surfaced more than 10 days ago when the residents of Kandivali's posh housing society, Hiranandani society approached the cops and claimed that they were cheated in the name of giving vaccines.
390 peole in the society took the jab and later found out that around 120 of them were given fake certificates and the rest didn't even get that. Since then, Mumbai police have filed 07 FIRs, have arrested 10 people, and are looking for two accused.
