Anti social behaviour -MARINA VIEW OFFICE PARK

Hi i am a new resident of portishead and i'm loving living here but there is something that is really getting on my nerves and not sure if it's a new problem or it's something that has been ongoing for awhile. It is the anti social behaviour at the marina office park because it is emptyit is being targeted by groups of teens in cars and there are using it to drink and smoke and genrally be rowdy.

Has anyone else seen,heard or know anything about this?
