A woman has been arrested on suspicion of neglecting a five-month-old boy who suffered a cardiac arrest at a theme park.
The baby is in a critical condition in hospital following the incident at Legoland Windsor at about 13:00 BST on Thursday, police said.
A 27-year-old woman from Witham, Essex, was arrested on suspicion of neglecting a child to cause unnecessary injury.
She has been released on bail until 26 July.
Det Con Zoe Eele, of Thames Valley Police's Child Abuse Investigation Unit, said: "Firstly, our thoughts are with the family of the boy who is in a critical condition in hospital after suffering a cardiac arrest.
"We are working closely with the team at Legoland Windsor Resort but would like to speak to anyone who have information about this incident, specifically anyone who was queueing for the Coastguard HQ boat ride between around 11.30am and 12:45pm.
"I would ask for the public to please avoid speculation about the incident and to respect the boy's family at this deeply upsetting time."
Police said they are not looking for further suspects in relation to the incident.
In a statement, the theme park said: "On Thursday, a young guest was taken ill... and our fully trained First Aid team administered immediate care until the emergency services arrived.
"We will continue to support Thames Valley Police with their ongoing investigation."
