Expat attacked in Shinas by bike hooligans

I was attacked on Friday evening by a bike hooligan by throwing a bottle at my neck. Every evening the speeding bikers with no registration and no insurance are a menace in the locality. I wonder if it is possible to alert the police higher ups and start police patrols to control the bikers. Also the ROP must consider making it mandatory to register any powered vehicle. Will someone take up the issue and alert the powerful people in government?
