Stephanie Davis is said to be the alleged victim of the assault claims that have been brought against ex-boyfriend Jeremy McConnell.
The model has denied any involvement with any assault.
Very few details about the investigation are known, but Merseyside Police have released a statement confirming they are looking into the report.
"Merseyside Police can confirm a report was received of an assault at a property on Thursday 9 March," a police spokesperson told the Mirror.
“Officers were contacted on Sunday, 12 March and an investigation into the incident is on-going."
"At this time no arrests have been made.”
"Jeremy denies any wrong doing, however he is fully cooperating with the police in their investigations,” according to Jeremy's rep.
According to The Mirror, it’s alleged that Stephanie was forced to call the police after Jeremy began behaving "oddly."
Stephanie then raised concerns from fans over some bruises which she documented in the bath on Snapchat.
There is currently no confirmation that these bruises are connected with the alleged assault in any way.
Jeremy has returned to Ireland to be with friends and family.
