The accused, identified as Kanchan Sahu (26), was held from office of Sahu Tours & Travels by the surveillance team of RPF, where he was generating e-tickets through fake identity cards, a senior official said.
The team also recovered unauthorised e-tickets worth Rs 26,808, a laptop and a mobile phone from the spot.
RPF is currently running an anti-tout drive to weed out black-marketing of railway tickets and has so far arrested 40 people and registered 30 cases in this regard.
He said that the accused used to get a commission of Rs 150-200 per ticket.
A case under relevant sections of Railway Act has been registered against Sahu, the official added.
