The Shiv Sena on Monday said that identity cards should be made compulsory in Mumbai too so that 'outsiders' are not allowed to enter the city without some sort of permit.

'The Delhi government has woken up to the threat posed by terrorists,' an editorial in the party's mouthpiece Samana said.

Defending the compulsion of ID cards, it says if the police stop somebody to check his/her identification papers, it does not impinge on the person's liberty. It also congratulated Delhi chief minister Sheila Dikshit and the Delhi police for making ID cards compulsory in the national capital.

The editorial also rails against 'floods' of migrants coming into Mumbai, and further says ID cards should be made compulsory in every city of the country.
