Police on Friday arrested an aide of Asaram's son Narayan Sai, who is wanted in a sexual assault case, for allegedly help him abscond.
Dharmesh, who was in-charge of self-styled godman.
Asaram's Ridge Road ashram, was nabbed in New Delhi on Friday morning from his hideout in a joint operation by Crime Branch of Delhi Police and Gujarat Police.
Police is expected to produce him in a local court in New Delhi.
He would be taken to Gujarat for questioning.
A team of Gujarat Police has been camping in Delhi since the last couple of days in search of Sai in connection with a sexual assault complaint against the father-son duo registered by two sisters.
On Wednesday, a joint team of Delhi and Gujarat Police had conducted raids at Asaram's ashrams at Rohini, Najafgarh, Jafarpur Kalan and on Ridge Road.
The sexual assault complaint against Asaram and Sai was filed at Jehangirpura Police Station in Surat.
According to police sources, the team from Surat landed in the national Capital after tracing Sai's location to the city while intercepting his mobile phone locations.
Police, however, could not make any headway in tracing the whereabouts of Sai, who they said, was frequently changing his location. There are apprehensions that he might have slipped into Haryana from Delhi.
Sources said Sai has been frequently switching his SIM cards and mobile phones. He has so far changed around 17 SIM cards and mobile phones, the sources said.
Surat Police had recently registered two complaints - one against Asaram, the other against Sai - of rape, sexual assault, illegal confinement and other charges as alleged by the two sisters.
The younger of the two sisters has filed the complaint against Sai, accusing him of repeated sexual assault between 2002 and 2005, when she was living at the Surat ashram.
