Security has been further tightened in city in the wake of proposed visit of President APJ Abdul Kalam and Gujarat Chief Minister Narendra Modi, who are visiting in the backdrop of Tuesday's serial train blast that killed 182 people.
In view of the security scenario in Mumbai and the threat perception to the dignitaries, police are leaving no stone unturned to ensure that the visits pass off peacefully.
