Goa [Images] government will write to the Union Home and External Affairs ministries asking them not to re-issue visa to Fiona Mackeown, mother of slain British girl, Scarlett Eden Keeling, for her anti-state campaign and her shoddy background.

"We are writing to the Home and External Affairs ministry not to issue her visa again to come to India. Her entry into India should be banned," Goa Home Minister Ravi Naik, who was accused by Fiona of having links with the drug trade, told media persons in Panaji.

He said the state is inquiring into her background and source of income.

"How can she travel with six children to India without any source of income? What was she doing frequenting in Karnataka? We are investigating everything," Naik said.

Fiona, whose daughter Scarlett was drugged, raped and allegedly murdered on Goa's popular Anjuna beach, had accused Home Minister and Director General of Police B S Brar of having links with the drug mafia in the state.

"We will request the Union government to make it sure that she does not get entry to India again," Naik reiterated replying to a question.

Fiona along with her children and a male partner had arrived in India in November on a six month tourist visa.

Asked whether Fiona would be prosecuted under Goa Children's Act for neglecting her child, the home minister replied in positive.

The home minister, admitting to illicit drug trade in the state, said the police had begun swooping down on inflicted areas.

According to Naik, Goa police's Anti-Narcotic Cell was doing tremendously good job and had booked several cases, curtailing the trade to a great extent.

Naik said he has already informed the Swiss embassy about trafficking of drugs to their country through a chartered flight from Goa.

"The drugs are transported to European countries through chartered flights from Goa airport," the state home minister said.
