NEW DELHI , India -- Police covered up the murder of a British teenage girl in Goa last month to protect the tourist industry , a state minister and local media said Monday . Scarlett Keeling stands on Anjuna beach in Goa a few days before her death . Officers had initially said Scarlett Keeling had drowned on Anjuna beach after taking drugs , but changed their story when the 15-year-old 's mother protested and a second autopsy suggested she had been raped and murdered . A suspect in the case was arrested Sunday but Fiona MacKeown said she did not believe he was the man who killed her daughter . `` This is a clear case of murder and it has gone out of proportion because the police tried to cover it up , '' Francisco X. Pacheco , Goa 's Tourism Minister told Reuters.com . Indian media suggested the cover-up was an attempt to protect Goa 's tourism industry . `` They should have arrested this man a long time ago and this issue would have got diluted , but now because of the tainted image of some police officers in the case , things have gone out of hand , '' Pacheco said . Police said they were investigating allegations of a cover-up and the actions of junior officers . `` There are certain things under my scrutiny and I have taken cognizance of all these issues , specially these officers , '' Kishan Kumar , a senior police officer overseeing the probe told Reuters . Keeling 's mother said she also believed police were trying to cover up the truth behind her daughter 's murder , and that they had arrested Samson D'Souza , 29 , to make it look like they were making progress in the case . `` We 've had an awful lot of contact with people that have been in this situation before , and they 've warned us to be careful ( that ) the police will try and find someone immediately to try and put a front on it that they 're actually doing something , '' Fiona MacKeown told BBC radio on Monday . Kumar described D'Souza as a `` local Anjuna boy '' who was a bartender at Liu 's , a beachfront bar . He said police had confirmed D'Souza 's role in Keeling 's rape and were now trying to find evidence that he killed the teenager . `` We have sufficient evidence to show that he was involved in rape , '' Kumar told CNN . `` So far as murder is concerned , we are investigating further . '' Scarlett and her family arrived in November for an extended vacation in Goa , known for its white sandy beaches and dance music scene . Beachfront shacks house the bars that fuel the nightlife . MacKeown said Scarlett was left in the care of a trusted male friend and his aunts while the rest of the family traveled to an adjoining Indian state , but she told the BBC that she has had no contact with the family since her daughter 's death . The mother said Monday she sent a letter to Goa 's chief minister asking for India 's Central Bureau of Investigation to look into the case . Goa is popular with Western tourists but several tourists have died from drug overdoses in recent years while women have been attacked and sexually assaulted .
