TRURO, England - Victims of acid attacks in the United Kingdom are calling on the government to enforce longer prison sentences and tighten controls on the sale of corrosive substances, after a jump in the number of cases last year and in 2017.

The issue hit headlines after a recent spate of attacks, including one in June in which two cousins were doused with acid through a car window as they were out celebrating a birthday, prompting Interior Minister Amber Rudd to review legislation.

There have been several acid attacks in London since, from robberies to gang-related violence.

The Home Office said it planned to set out guidance for prosecutors on classifying corrosive substances as dangerous weapons and to review sentencing guidelines.

"Other key actions will include a review of the Poisons Act to assess whether it should cover more acids and harmful substances and further work with retailers to agree measures to restrict the sales of acids and other corrosive substances," said Sarah Newton, minister for crime, safeguarding and vulnerability.

For victims like 32-year-old Andreas Christopheros, who was assaulted at his home in 2014, that may bring little comfort. But he joins a chorus of acid attack survivors demanding that tough words become reality.

"I believe the UK has got its strategy toward this completely wrong," he said at his home in Truro, a seaside town in southwest England.

"I strongly believe that the sentencing for anyone who carries out any form of acid attack, whether their intended victim is injured badly or not, should serve a life sentence, with a minimum term of 20 or more years."

Ninety percent of his face has been reconstructed using skin from other parts of his body, including his scalp and neck. He has had between 10 and 12 surgeries and will need more, he said.

He has lost his eyelids three times as the scarring on his face contracts, making sleep a constant struggle.

Crimes using corrosive substances in London jumped in 2016 to 431 from 261 in 2015, Metropolitan Police numbers show. So far this year, there have been 282.

Jaf Shah, executive director of London-based nonprofit Acid Survivors Trust International, described a "loophole" in the law whereby people possessing acid would not be charged but those carrying a gun or a knife could.

"There just aren't appropriate levels of controls around acid," Shah said. "If you are caught with acid, police have to prove intent, which is very difficult."
