He said majority of those with such (shabby) attire are domestic tourists who arrive in the state in a jeep, don't book any hotel to stay and venture on the beaches in their undergarments creating nuisance for women.
"They pull foreigners towards them to click picture," he said.
"There should be some control on these stupid tourists or else good tourists will stop visiting," he said, adding that such visitors creating nuisance should be arrested.
Lobo alleged that India Reserve Battalion (IRB) police personnel posted on the beaches were extorting money from businessmen and vendors at the shore.
"There are 300 IRB personnel posted on the beaches but they are busy collecting haftas (extortion money)," he charged.
Last month, state public works department minister Sudin Dhavalikar had demanded a ban on the bikinis in the state, claiming that women in skimpy dresses might create a law and order problem.
