An Everett guy charged with beating a man with a baseball bat on the North Washington Street Bridge Friday morning was ordered held in lieu of $15,000 cash bail, the Suffolk County District Attorney's office reports.

Should Travis El-Saadi make bail, he is forbidden from driving the gold Acura from which he alleged jumped out with a baseball bat and which he liked to post photos of on his Facebook page, at least until after the charges of armed assault with intent to murder, assault and battery with a dangerous weapon causing serious bodily injury and assault and battery with a dangerous weapon are resolved, the DA's office adds.

According to the DA's office, bystanders flagged down police at North Washington and Causeway streets shortly before 9 a.m. on Friday to help a man just lying in the middle of the intersection, blood pouring out of a deep cut in his head and other injuries:

Witnesses informed police that a gold Acura pulled in front of the victim, who was on his scooter, just before Causeway Street. A man in his 20s exited, approached the victim, and beat him with a baseball bat before returning to his vehicle and fleeing the scene. A witness recorded part of the incident on a cell phone, and additional witnesses were able to provide the license plate number of the suspect vehicle. Based on that information, police determined that the vehicle is registered to a relative of El-Saadi, prosecutors said. ... The victim told police that the man who attacked him had been driving erratically and allegedly threw coins and attempted to spit at him prior to the incident. The victim was attempting to capture the vehicle’s license plate number when the man attacked him, prosecutors said. El-Saadi was later identified from a photo array.

Police arrested El-Saadi at the Dorchester auto-body shop where he worked later in the day, the DA's office reports.

The 49-year-old victim was taken to a local hospital and is expected to recover, the DA's office says.

Innocent, etc.
