Proposals to ensure acid and other corrosive substances can be classed as dangerous weapons have been unveiled by the Government.
The move is part of a new strategy to crackdown on acid attacks following a recent spate of high-profile incidents, including five assaults that were linked in London on Thursday.
The Home Office said it will work with police and the Ministry of Justice to assess whether powers available to the courts, including sentencing, are sufficient.
Possession of acid or other corrosive substances with the intention to do harm can already be treated as possession of an offensive weapon under the Prevention of Crime Act, which carries a four-year maximum penalty.
Crown Prosecution Service's (CPS) guidance to prosecutors will now be reviewed to ensure it makes clear that acid and other corrosive substances can be classed as dangerous weapons, and what is required to prove intent.
The Poisons Act 1972 will be assessed to consider if it should cover more harmful substances, while retailers will be asked to agree to measures to restrict sales of acids and other corrosive substances.
New guidance will also be issued to police officers on preventing attacks, searching potential attackers for harmful substances and responding to victims at the scene.
More than 400 acid or corrosive substance attacks were carried out in the six months up to April 2017, according to figures from 39 forces in England and Wales.
Bleach, ammonia and acid were the most commonly used substances, the Home Office said.
Sarah Newton, minister for crime, safeguarding and vulnerability, will outline the Government's strategy on combating acid attacks in the Commons on Monday.
Home Secretary Amber Rudd said: "Acid attacks are horrific crimes which have a devastating effect on victims, both physically and emotionally.
"It is vital that we do everything we can to prevent these sickening attacks happening in the first place.
"We must also ensure that the police and other emergency services are able to respond as effectively as possible, that sentences reflect the seriousness of the offences and victims are given the immediate support they need."
