Mumbai, Sep 22 (PTI) : The Western Naval Command here issued a high alert along the Mumbai coast after four men in military uniform were today spotted moving suspiciously near a Naval facility in Uran, about 47 kms from here.

A search is on to trace the four men, police said. According to Indian Navy Chief PRO Capt D K Sharma, the search operation is going on along with Maharashtra police after the matter came to light.

The Western Naval Command (WNC) issued "the highest state of alert" along the Mumbai, Navi Mumbai, Thane and Raigad coasts after suspicious movement of a group was reported in Uran.

The WNC has roped-in the police and Coast Guard also for the task.

According to initial information received by the authorities, four school students spotted a group of people dressed in uniform similar to that of Indian Army near Uran and Karanja area.

The DGP office immediately issued alerts to all police stations along the coast.

Security has been beefed up at sensitive locations along the coast, including the Gateway of India, Raj Bhawan, Bombay High (rig), Bhabha Atomic Research Centre and other major establishments near the sea.
The Maharashtra police has also issued an alert following the information that some suspects were moving around near Uran, Director General of Police Satish Mathur told PTI here.

All the coastal police stations in the state have been put on alert and police teams are working in coordination with the Navy in search operations, he said.

Mathur, however, was quick to point out that no suspect has been traced so far.

Notably, the coastline is guarded by a three-tier network which starts with the local police (with its coastal police stations) closest to the land, followed by the Union Home Ministry-led Coast Guard while the Indian Navy patrols the high seas.
