The victims were identified as 30-year old security guard Dasharath and 25 year-old office boy Shubhankar Das.

FoxMandal Bangalore partner Shymal Mukherjee said: "We are truly shocked about the entire issue over here."

Dasharath was found murdered with stab injuries and Das was found dead inside the office premises, recounted Mukherjee. He explained that the majority of the office space had been locked but that night-staff had access to certain parts of the premises.

Mukherjee said that the intruder did not seem to have entered with the intention of theft as nothing appeared to be missing from the office.

But he added: "Neither can we fathom anything right now. The investigation is going on at a very high level.

"As of now, we are absolutely clueless about the motive."

Mukherjee said that all four Bangalore office locations would remain closed today as a mark of respect to the firm's "very trusted workers".

The murders occurred in one of the firm's four locations on Primrose Road.

According to the Deccan Herald, which first reported the news last night, FoxMandal Bangalore's reception, corporate and labour law teams are based there.

The Times of India also reported the story early this morning.
