"All the persons of unknown origin who are not in any way connected or linked to the constituency should be asked to vacate the areas," BJP's Goa spokesman Wilfred Mesquita said in a letter to the EC.

BJP has also claimed that flying squads in constituencies like Sanguem, Valpoi, Poriem and Cuncolim are non effective because of the connivance of local police with the ministers, contesting elections.

Mesquita has demanded that CRPF should be deployed for ministers with Z category to curb such things.

"Even the current batch of policemen with flying squads should be replaced by a new one," he said.

Considering the volatile situation in a few constituencies, the party has demanded that seats including St Andre, Taleigao, Shiroda, Sanguem, Valpoi and Cuncolim should be declared sensitive.
