The documents do not detail the nature of the assault on new girlfriends Kyra Grieve and Jessica Kay.
Spurned lovers Naomi Harrison, 23, and new partner, 21-year-old Danielle Hubbard, had decided to force their way into Grieve’s house where they knew they would be staying.
Harrison had dated both Jessica Kay and Kyra Grieve, while Hubbard has also dated Kay in the past.
Jessica, 22, looked out of the bedroom window and saw her former partners damaging her car before they bashed Kyra’s front door in.
Harrison and Hubbard had decided to go the house in Blackburn, Lancshire, to confront the couple who had ‘hooked up’ in March.

The pair admitted charges of assault and criminal damage at Blackburn Magistrates’ Court.
Kyra had kept Harrison’s belongings including a passport and birth certificate, and the pair had decided to get them back using force, a court heard.
Harrison’s defense attorney, Aftab Bakhat, said she had been in a relationship with Kyra for five years before meeting Hubbard.
They both told their respective exes who then formed a relationship of their own.
He said: “My client says Miss Grieve made it her business to keep hold of her personal documents such as passport and birth certificate and her clothing and she still has items.
“On this night, out of frustration and having had a drink, she went round to get her property back.”
Mr Bakhat added: “She has now applied for all her documents separately and wants no further contact with the aggrieved.”

Both were slapped with restraining orders preventing them from contacting the victims for two years.
