A three-year-old boy has been discharged from hospital after he suffered serious burns in a deliberate acid attack.
The toddler was in a pushchair with his family in a shop in Worcester, England, when a corrosive substance was "thrown or sprayed" over him, according to local police.
He was treated in hospital for burns to his face and one arm before being released yesterday afternoon.
Chief Superintendent Mark Travis said the boy was recovering at home with his family, who are being supported by specialist officers.
"A young family were out shopping and a substance appears to either have been thrown or sprayed towards a three-year-old child who was in a pushchair," he said.
"We are uncertain about the long-term implications of those burns, but we do hope that these won't be life-changing injuries."
Supt Travis renewed the appeal for information about three men seen in images released by police.
"We are really, really keen that the images we have released will hopefully bring forward information about people who may be able to help us, who were in the store at the time of the incident.
"If those people can come forward or people could identify those people it will help us understand the motivation for this."
He said the men were in the shop at the time of the attack and were "in very close proximity to the little boy".
They left the store in the direction of the city centre and he urged anyone who has seen "anything discarded in the area" to come forward.
The incident occurred at around 2.15pm on Saturday in the Home Bargains store on the Shrub Hill Retail Park in Tallow Hill.
A 39-year-old man from Wolverhampton has been arrested on suspicion of conspiracy to commit grievous bodily harm and remains in police custody.
Worcester City Council leader Marc Bayliss described the attack as "absolutely pure evil", adding: "I have never heard of an acid attack in Worcester."
