Goa/IBNS: A manager of a luxury hotel in Goa has been arrested for allegedly murdering his wife after she accused him of having an extramarital affair, reports said.

The accused, 29-year-old Gaurav Katiyar, tried to cover the murder as an accident as he claimed that his wife drowned in the sea when he was away.

Gaurav Katiyar works as a manager at a luxury hotel operated by Marriott International in South Goa's Colva.

Hailing originally from Lucknow, Katiyar married Diksha Gangwar about a year ago, but their relationship remained strained, reports said.

According to reports, Gaurav took his wife to the South Goa breach for a stroll on Friday afternoon where he drowned her.

When some tourists saw him coming back to the beach alone, they informed the police on suspicion.

They told police that they saw Gaurav and Diksha venturing into the waters, but then the man returned alone and the woman was nowhere in sight.

Katiyar tried to pass it off as an accident, but a video shot by a tourist exposed his claims.

The video showed him walking back alone to the beach and then returning to the sea apparently to ensure whether his wife was dead.

"The woman's body had injury marks, suggesting signs of struggle," officials told the media.

Police said the man has been arrested and an investigation is on.
