Jeremy McConnell has been arrested on suspicion of assault and criminal damage.
The 27-year-old model is in police custody waiting to be questioned after he "voluntarily attended" a Merseyside police station over claims he assaulted former 'Hollyoaks' actress and on/off girlfriend Stephanie Davis.
A spokesperson for Merseyside Police said: "Following a report of an assault at an address in Stephenson Grove, Rainhill, a man has this morning (16.03.17) been arrested.
"A 27-year-old man from Liverpool city centre has been arrested on suspicion of assault and criminal damage after voluntarily attending a police station on Merseyside. He remains in police custody for questioning."
Whilst a source added to The Sun newspaper: "Jeremy has flown back to Liverpool for questioning. He is continuing to cooperate with officers as they investigate the claim further. He's hoping to fly back to Ireland later this evening."
It comes after Jeremy was involved in an alleged altercation with Stephanie - the mother of his child Caben-Ali - in Liverpool on March 9 with Stephanie giving a statement to police on March 12.
A police spokesperson said at the time: "Merseyside Police can confirm a report was received of an assault at a property on Thursday 9 March.
"Officers were contacted on Sunday, 12 March and an investigation into the incident is on-going. At this time no arrests have been made."
In a recent Snapchat post, Stephanie showed off a series of bad bruises on her legs as she took a bubble bath, captioning the post, "Trying to relax."
Jeremy had been spending time in Ireland following the recent deaths of his father and his aunt.
Meanwhile, a representative for Jeremy has insisted the 'Celebrity Big Brother' star is "fully cooperating" with police.
They said: "Jeremy denies any wrong doing, however he is fully cooperating with the police in their investigations."
