The actor, who plays Kat Slater in the long-running soap, was taken into custody over the weekend for “public disorder”.
The statement reads: “Senior bosses have spoken to Jessie Wallace about the incident and issued a clear warning that this kind of behaviour is unacceptable and Jessie has expressed her deep regret.”
According to the publication, the incident occurred after Wallace attended a Madness gig in Thetford Forest, Suffolk, on Saturday evening.
Later in the evening, the actor and her companion were reportedly seen arguing outside a nightclub with police.
A police spokesman confirmed that a 50-year-old woman was cautioned after being held on suspicion of assaulting a police officer and drunk and disorderly conduct.
Wallace is said to have accepted a caution, following the incident.
The actor was reportedly suspended from the show in January 2020 for allegedly being “tipsy” and “verbal” while filming the 35th anniversary episode.
At the time, a BBC spokesperson said: “We don’t comment on artist’s contracts.”
