One person was arrested on Sunday in connection with the death of a 15-year-old British girl, who was found dead on a beach here. The Goa police filed a case of murder following a second autopsy on her body.

“We have arrested one person and more arrests will be made soon,” said Inspector General of Police Kishan Kumar.

The state police had earlier in the day detained three persons in the connection of murder of Scarlette Eden Keeling.

While police had throughout maintained that the case was that of accidental death, a second autopsy report has changed the course of investigation with the police registering the death as murder.

Scarlette was found dead on Goa’s popular Anjuna Beach on February 18 in a semi-nude condition. Her family members suspect that she was raped and murdered.

After the media focus and political lobbying, the state government had ordered a second autopsy which recommended that the death be investigated as “murder.”

The second autopsy into the death of the girl showed she had received over 50 bruises, as against the first autopsy report which showed five bruises on her body. The second autopsy showed half of the 50-odd bruises the girl had on her body were ante-mortem.

“We have registered the case under 302 of the IPC which means we are probing her death as a murder,” said North Goa Superintendent of Police Bosco George.

George, along with the team offficials, including investigating officer Braz Menezes, rounded up three suspects in the afternoon.

Police sources confirmed that a gang of seven boys is suspected to be behind the incident as they were seen with her a few hours before her death. The investigations have revealed that Scarlette was partying with these boys at a local shack till 4 am on the fateful day.

Sub-inspector Nerlon Albuquerque, who was initially investigating the case that was later handed over to Inspector Braz Menezes, is in the line of fire after the state Tourism Minister Fransisco Pacheco sought his dismissal.

The pressure seems to be mounting on the police to pull up the sub-inspector who is of the view that the death was due to drowning despite several evidences of murder.

“They lied all this. They misled us and the media,” Scarlette’s mother Fiona Mackowen said on Saturday night.
