Detectives say 'speculative' comments about Ursula Keogh 'could constitute a criminal offence'.
Detectives investigating the death of a Halifax schoolgirl have asked people not to post abusive or 'speculative comments' on social media.
The body of 11-year-old Ursula Keogh was found in the River Calder at Paris Gates on Monday 22 January.
She had gone missing from her home in Halifax earlier that day.
An inquest into her death is due to open on Tuesday 30th January.
A West Yorkshire Police Spokesperson said: "Officers continue to investigate the circumstances at the direction of the Coroner.
"We would ask people not to post speculative comments via social media as they could undermine the ongoing enquiries and if they are abusive in nature, they could constitute a criminal offence.
"Her family are being supported by specialist officers and have requested for privacy at this extremely difficult time."
