Mumbai: On a day when BJP President Amit Shah reached the city, Mumbai Congress chief Sanjay Nirupam on Wednesday accused the police of stalking him without any reason.

Nirupam said a huge posse of policemen was stationed outside his Andheri home since dawn.

"As I stepped out to go to my office, I was trailed by several police vehicles. When I asked police the reason, they said there were 'orders from above'," Nirupam told IANS.

He said that several Congress activists too are facing a similar situation, though the opposition party had not planned any protests against Shah during his Mumbai trip.

"This is nothing but a violation of citizens' privacy by misusing police and government machinery against opposition leaders. The BJP leaders are scared of the opposition," Nirupam said.

Shah was accorded a warm welcome at Mumbai airport by Chief Minister Devendra Fadnavis and Mumbai Bharatiya Janata Party chief Ashish Shelar and others.

During his visit, Shah is likely to meet Shiv Sena President Uddhav Thackeray, Bharat Ratna awardee Lata Mangeshkar, former actress Madhuri Dixit, and industrialist Ratan Tata among others as part of the 'Sampark for Samarthan' initiative.
