A man who attempted to sneak into the high security ISRO-run Propulsion Complex at Mahendragiri, near here, was arrested on Sunday, police said.
The man was spotted attempting to enter the state-of-the-art centre for ISRO's space research programme. The security guards caught hold of him and the Indian Space Research Organisation (ISRO) officials subsequently handed him over to the police.
Police said they were interrogating the man and refused to divulge further details.
