Police tracked down and arrested several rowdy off-road bikers Saturday on a busy highway in Massachusetts.

Boston Mayor Marty Walsh said in a statement the bikers have been causing a ruckus in the city and also a safety concern, which led to their arrest on Interstate 93 South.

'They caused a lot of problems. It was a nice day yesterday and they decided to take it on the highway and seven people were arrested,' Walsh said, according to CBS Boston.

The bikers, who were also on all-terrain vehicles, were seen swerving through traffic in newly-released footage as police pulled up behind the crew and one officer fired his weapon.

CBS Boston reported that one of the bikers was hit, but is said to be OK.

Several other drivers on the highway were forced to stop as the bunch carelessly cruised around.

'I think they're getting a little bold and they figure we can do this on our highways and that's a major concern,' Walsh said.

As many as 20 off-road vehicles were pulled from the road during the incident.

Aderito Monteiro, 28, pleaded not guilty to numerous charges Monday in court. The remaining six who were arrested are expected to appear in court on Tuesday

'Hopefully they'll think secondly about putting something like that on the highway again,' Walsh added.

The seven individuals who were arrested are currently facing charges.

Aderito Monteiro, 28, of Randolph, was pictured Monday at his arraignment for disorderly conduct, negligent operation, driving an uninsured ATV, failure to stop for police, marked lanes violation and operating an unregistered all-terrain vehicle.

Monteiro pleaded not guilty to the offenses and has been jailed on $2,000 bond.

The remaining individuals who were arrested are expected to appear in court on Tuesday.
