New Delhi:  Suspected to be snooping outside the ousted CBI Chief Alok Verma’s residence,

four men were held by the security personnel posted at the place on Thursday morning.

It is being said the four men were allegedly trying to spy on Verma, who was sent on leave in the wee hours of Wednesday while an interim director was brought in his place.

The men, suspected to be from an intelligence agency, who were caught were taken inside the Verma’s residence complex.

Verma, who was abruptly sent on leave following a midnight government order, was working on several important complaints and has challenged his removal in the Supreme Court and his plea is to be heard on Friday.
