A $5,000 reward has been posted as police continue to search for a man allegedly involved in the attempted murder of Lady Gaga’s dog walker, after he was accidentally released from jail.

James Howard Jackson was being held on an attempted murder charge but was released from a jail in Los Angeles “due to a clerical error”, a sheriff’s department said in April.

Months later the 19-year-old continues to elude police, who are now offering $5,000 (£4,100) reward for information leading to his arrest.

Jackson is one of three men charged with also stealing two of the star’s French bulldogs in February 2021.

Prosecutors say Jackson and two other alleged gang members had driven around looking for expensive French bulldogs to steal on 24 February last year.

They then spotted, tailed and robbed Ryan Fischer as he walked the dogs belonging to Lady Gaga near Sunset Boulevard, it is alleged.

During a violent struggle, Fischer was hit, choked and then shot in an attack caught on camera by the doorbell camera of a nearby home, prosecutors say.

The video recorded the dog walker screaming “Oh, my God! I’ve been shot!” and “Help me!” and “I’m bleeding out from my chest!”

The US Marshals said Jackson should be considered as “armed and dangerous” and urged anyone with information on his whereabouts to report it to police immediately.
