Lanza had attended a function at a hotel in the Kudapaduwa area when a ball being played with by some resident youth had hit his vehicle.
According to reports, a verbal exchange between the mayor and the youths had ensued and a father of one of the youths was assaulted as a result. The enraged son had immediately beaten up Lanza.
Residents say that Lanza had also been under the influence at that time.
Since ASP Eric Perera is currently stationed in the Negombo police area, residents expect the police to hold impartial investigations and deliver justice, the regional news website 'Meepura' notes.
