Sahil Zaroo, an accused in the Rahul Mahajan drug case, was arrested today for allegedly slapping his girlfriend and Jannat heroine Sonal Chauhan at Mumbai's Chhatrapati Shivaji International airport, the police said.

Zaroo, 24, confronted Chauhan last evening when she was collecting a boarding pass for a Hyderabad flight.

"It resulted in a minor altercation between the two during which Zaroo slapped Chauhan in public and also threw her mobile phone on the floor," said a senior officer from the Santa Cruz airport police station.

After the incident, Zaroo, who had booked a ticket on the same flight, started running. The CISF officials posted at the airport caught hold of him immediately. Chauhan's father, who had come to see her off at the airport, assaulted Zaroo when he was being taken away by security, the officer added.

"She knew Zaroo for some time and was avoiding him lately due to which he would send her obscene SMSes," he added.

Zaroo was arrested under Sections 323 (causing hurt), 354 (outraging modesty of a woman), 448 (tres-pass), 509 (insulting modesty of a woman) and 427 (causing damage) of the Indian Penal Code.

Zaroo, whose family owns a shawl business, is alleged to have sold cocaine to late BJP leader Pramod Mahajan's son Rahul and his secretary Bivek Moitra in Delhi in 2006. Moitra died due to drug overdose while Rahul had to be hospitalised.
