The vehicle's front and back windscreens, as well as the side-mirrors, were smashed in the incident.
A police report has been lodged on the matter.
DBKL, in a statement posted on its Facebook page, said the operation was conducted in two areas involving massage centres and prostitution rings.
The operation saw the premises involved being sealed while 23 units of equipment used for immoral activities were confiscated.
DBKL said that the premises owner attempted to bribe enforcement officers RM10,000 but he was unsuccessful.
"We pledge full cooperation to assist PDRM in this case (vandalised van) and will continue to perform enforcement from time to time," said DBKL Enforcement Department senior deputy director Osman Ismail.
