Justin Bieber was reportedly caught on tape at the time of the egg attack on his neighbour's house.
New surveillance footage showing the 'Boyfriend' singer near the property in Calabasas, California - which suffered an estimated $20,000 of damage in the incident - when it was hit by eggs last month is being considered as critical evidence in the case against the star.
According to gossip website TMZ, Justin isn't seen holding any eggs but he is reportedly heard shouting abuse at his neighbour.
In the short clip, a man thought to be Bieber is heard shouting: "F**k you! I got another one for you actually."
However, sources close to the star have disputed the authenticity of the video, which is too dark to clearly make out the 'Baby' hitmaker.
The reports come after the Los Angeles County Sheriff's Department passed the case on to the Los Angeles County District Attorney and strongly recommended that the 'Beauty and a Beat' singer be punished to the fullest extent of the law.
The District Attorney is expected to make a decision on the case - which was originally filed as a misdemeanour but could become a felony due to the extent of the damage - in approximately one week.
