3 men arrested over acid attack on British boy

Three more men were today arrested by British police after a three-year-old boy suffered serious burns in a suspected acid attack in central England.

The boy was treated in hospital for serious burns to his arm and face after an "acid or a corrosive substance" was either "thrown at or sprayed towards him" at a discount store in the city of Worcester, according to police.

The men, aged 22, 25 and 26, were arrested in London on suspicion of conspiracy to commit grievous bodily harm. Earlier, a 39-year-old man was arrested on Sunday on suspicion of conspiracy to cause grievous bodily harm remains in police custody, the BBC reported.

"We'd like to thank everyone who shared our appeal over the weekend and contacted us with information; all of this is helping us to build up a better picture of this incident, detective inspector Tony Garner said.

"The shock will be universal. Anyone conducting such an attack on a small child is just appalling", Robin Walker, member of parliament for Worcester added.

Britain has seen a spike in the number of acid attacks in recent years, with hundreds of incidents in London alone every year.

The trend has prompted government intervention initiatives while police have asked the public for help to try to tackle the problem.
