Kieran Hayler has been arrested on suspicion of child neglect and possession of a firearm with intent to cause fear of violence.
The 36 year old was married to former glamour model Katie Price from 2013 until 2018.
They share two children together, nine-year-old son Jett and daughter Bunny, eight.
A spokesperson for Sussex Police confirmed: “A man has been arrested on suspicion of possession of a firearm with intent to cause fear of violence and child neglect.
“He has been taken into custody for questioning. We will not be commenting further.”
A source close to Kieran also told the Mirror that he was assisting officers with their enquiries.
He lives with his fiancé Michelle Penticost, 41, their one-year-old son and Michelle’s son.
Katie and Kieran finalised their divorce in June 2022 after whirlwind romance.
The pair started dating at the end of 2012 and married in the Bahamas the following January before calling it quits on their relationship five years later.
As well as being mother to Jett and Bunny, Katie is also mum to Harvey, whose father is Dwight Yorke.
She also shares son Junior and eldest daughter Princess with ex-husband Peter Andre.
Katie is reportedly back with her on-off partner Carl Woods.
The mother of five was once again wearing her engagement ring from the car salesman, 34, in a snap posted to her Instagram Stories after a rocky romance.
Since beginning their relationship in 2020 and getting engaged a year later, Katie and Carl’s relationship has hit the headlines.
Sharing an Instagram Story with her 2.6million followers recently, Katie snapped a picture of her left hand resting on her inked leg, once again sporting her engagement rock.
Before that, the Page 3 icon and her on-off fiancé followed each other on Instagram again.
Daily Star has contacted representatives for both Kieran and Katie for a comment and Sussex Police.
