A day after the robbery at the Shalimar Garden branch of Muthoot Finance, the police have zeroed in on more than 10 former and current employees of the company who could be involved in the case.
On Saturday, about 10 armed men robbed the company of gold and R6 lakh cash.
Senior superintendent of police (SSP) Raghubir Lal said seven of the 10 employees were sacked a couple of months ago.
"Three of the current employees have been detained. But the company, so far, have not provided any personal details about the past employees," the SSP said.
The police said they were working in close coordination with the Delhi Police.
"We have come to know about the involvement of former employees in other incidents at other branches of this company," Lal said.
