Four persons including two delivery boys were arrested for allegedly molesting and groping a young woman on New Year Day here, Bengaluru Police Commissioner Praveen Sood said on Thursday.

The four are Ayyappa, Leno, Somashekar and Sudhesh and are in the age group of 19-24 years.

"We are on the lookout for two more of their accomplices as six men planned the heinous incident which they planned together after stalking the victim after the new year party that night," Sood told reporters.

Ayyappa is the main accused who groped the victim while Leno molested her soon after forcing her on the scooter.

"We have also recovered the scooter on which the two rode towards the victim and attempted to abduct her while the other accomplices were watching them committing the crime from a distance," Sood said.

Pleading the media not to ask for any information about the victim who has been traumatised by the incident, Sood said though all the accused were from the same locality (Kammanahalli), the victim did not know them as she had come to Bengaluru only a week ago.

"Ayyappa, 19, is a delivery boy, Leno is a college student, Somashekar is a driver and Sudesh is another delivery boy," said Sood.

The accused would be produced before a court on Friday for four-five day police custody to interrogate them.

They have been charged with wrongful restraint and sexual harassment.
