Hyderabad, Aug 18 - Andhra Pradesh police Tuesday arrested one of their own - a sub-inspector of police - for allegedly cheating a college student after promising to marry her.

Ranganath Goud, who was absconding since the student lodged a complaint against him last month, was arrested by Guntur district police - three days after Razia Sultana, 18, began an indefinite fast outside the office of Guntur district superintendent of police, demanding senior police officials intervene to make Goud marry her.

The relatives and friends of the police officer, however, staged a protest against the arrest. They alleged that the police were trying to force him to marry Razia.

Earlier, Goud escaped from a hotel in Guntur town after some media persons reached there on learning of his presence.

Razia alleged that the police officials were not taking any steps to either arrest Goud or convince him to marry her though she lodged a complaint against him two weeks ago.
