Additional Sessions Judge Ruby Alka Gupta sent the 54- year-old accused, Murray Denis Ward, to jail after Delhi Police said his further custodial interrogation was not required.
The police said Ward had been associated with NAB as a regular donor for almost nine years and was a frequent visitor to the institute.
He was arrested for allegedly inappropriately touching three NAB inmates on September 2, police said.
He had suffered a paralytic attack in February and has been under treatment since then. He was staying alone here while his family is in the UK. Police suspect that he is a paedophile.
