The nightclub brat who shot/killed a patron at point blank range is the younger brother.
Further:
My Thai son worked for a short while at one of the clubs/bars/discos at RCA. Never a dull moment with fighting patrons/fighting personal bouncers etc.
The owner of the club where my son worked frequently held 'pep talk' sessions with/for the bar staff. One item mentioned every time: 'if the Chalerm sons handgun toting gang come in never discuss anything with them, listen very carefully to their drink orders, be sure your respond with yes sir quickly and serve the drinks quickly and be sure no mistakes. Never ask for money. Put the drink(s) on the bar and move back.
There was an incident on the stairs with the shirt sleeve of one barman accidently slightly touching the shirt sleeve of one of the brothers. Bouncer instantly punched the barman in the mouth several times, blood everywhere, professional ambulance from a nearby hospital called and arrived. Ambulance staff don't want to attend the injured boy when they realize they are surrounded by the brothers and their bodyguards.
Injured barman got himself up and ran for a door, other staff quickly got him into the parked ambulance which departed quickly and straight to the hospital. Hospital called police and asked for a team of police to come quickly to protect the injured boy and hospital staff.
Bar owner paid all the medical expenses.
My son (rugby player) came home upset, told me the details and said 'dad I don't want to go back there'. I quickly responded 'You're not going back' and at the same time promised him a quite large increase in his monthly allowance.
