The Palm Springs Police Department wants to talk to an old friend, Jeremy London.

The former Party of Five star has been accused of assault. The accuser, Breaking Celebrity News has exclusively learned, is none other than his ex-wife Melissa Cunningham.

The cops have not released Cunningham's name, saying only that a London "girlfriend" contacted them, claimed an argument over the custody of their child became violent outside her Palm Springs home, and she had been injured.

London and Cunningham have a son, Lyrik, 4 who is in the custody of Melissa's mother.

"London has not yet surrendered himself to the police and we currently have patrol and detectives investigating the case further," Sgt. Reed from the Palm Springs PD tells Breaking Celebrity News exclusively.

"A warrant has not yet been issued for his arrest in the alleged assault but depending on what happens during the course of the investigation, then that may be an option. Under California law if a person assaults their spouse or the mother of their child then it is a felony.

"During the argument London had with the woman, she sustained minor visible injuries to her hand but refused emergency care."

As Breaking Celebrity News reported extensively last year, London and Cunningham had a tumultuous relationship with him telling us she is "a very sick person."

The comment followed London's bizarre episode where he was kidnapped by drug dealers, and forced to take drugs himself.  Few believed his story -- including Melissa -- but the tale was proven to be true when one of the men was arrested.
