A woman and two children are in hospital following a suspected poisoning attack at a home in Sussex.
The 38-year-old and youngsters aged nine and 13 remain in a “serious but stable condition”.
A woman has been arrested on suspicion of administering a noxious or poisonous substance to cause injury.
Sussex Police said it is investigating the “isolated incident” in Hunters Way, Uckfield on Thursday morning.
A spokesman added: “While their conditions remain serious, they are currently in a stable state.
“A woman has been arrested on suspicion of administering a noxious substance / poison to cause injury.
“We are not searching for anyone else in relation to this investigation.
“Our enquiries are ongoing and a heightened police presence is anticipated in the area at this time. This is being treated as an isolated incident with no threat to the wider community.”
Councillor Dan Manvell, who represents the town’s north ward, told The Independent the local community is shocked.
He said: “It is obviously something which doesn’t usually happen in Uckfield.
“Nothing more than low level antisocial behaviour occurs here, so this is worrying.
“It looks like an isolated incident but I’m sure it is upsetting for all those involved, including the family. I hope they get better soon.”
Uckfield has a population of around 15,000 people and sites between Brighton, Eastbourne and Tunbridge Wells.
South East Coast Ambulance Service declined to comment.
