Three men in their 20s have been arrested in England in connection with a suspected acid attack on a three-year-old boy.
The incident happened on Saturday afternoon in a store in a retail park in Worcester.
The boy, who was in a pushchair when the incident happened, was hospitalised with serious burns to his arm and face.
He has since been discharged, but police say "the long-term implications of his injuries are unknown at this time".
Police have said they are treating the incident as a 'deliberate attack'.
It has been confirmed today that three men - aged 22, 25 and 26 - have now been arrested.
They are being held on suspicion of conspiracy to commit grievous bodily harm.
A 39-year-old man also remains in custody in connection with the incident.
Tony Garner of West Mercia Police said: "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."
