Officers have warned that people could face police action for posting "malicious" comments about the death of a 2-year-old girl who was left in a car that rolled into a river.
Kiara Moore was recovered from a silver Mini that had gone into the river Teifi in Cardigan, Wales, on Monday.
Dyfed-Powys Police, which led the search for Kiara after the car was reported missing with her in it, warned people to "think very carefully" before posting and not to speculate. "We are aware of comments on threads across social media which are being looked at.
"Posts considered to be malicious will be recorded and police action may follow."
Kiara's parents, Kim Rowlands and Jet Moore, initially believed the car had been stolen after it vanished with Kiara inside from near a slipway leading to the river.
