Loud music / parties is increasingly becoming a nuisance for DHAC residents but DHAC or SECURITY & VIGILANCE seems helpless, why?

Playing of loud music / late night parties is equally a concern for DHAC, as is for residents. S&V responds to the complaint but usually the volume is reduced on he avoids of S&V but it all gets resumed as and when our staff depart the scene. Police is involved but owing to the nature, police also does not take any hard steps, which sometime encourage people to continue.
