"It is very unfortunate that Goa is turning into a sin city. There is alarming growth in casino activity, gambling, prostitution and drug menace," Faleiro claimed while talking to reporters here.
The leader said Congress is working out a plan to take up the issue at the national level against casinos operating in river Mandovi and escalating instances of substance abuse.
Admitting that it was the Congress-led government that allowed casinos in the state, Faleiro slammed the ruling BJP-led government for failing to move out these vessels from river Mandovi.
Faleiro said 80 per cent of visitors in casino are Goans and tourists come here to gamble only during weekends.
