Preliminary investigations reveal that the Sunday theft at Mahim Electrical Sub Sectioning station is the third such incident reported here.
The station, located in Mahim East at the corner of a railway colony, has two separate substations — one for the WR and the other for CR — located less than 20 meters apart.
The RPF, the GRP and the local Shahu Nagar police are now investigating the theft.
According to a senior divisional railway security official at the CR sub station, 55 batteries, each weighing about 30 kg, were reported stolen on May 1.
“The subsequent day on May 2, at the WR’s sub station, 55 batteries were again stolen. A WR worker noticed that the main gate had been breached. The incident was reported before the electricity could trip and affect services,” said a senior security official.
Each substation has a high steel fence with barbed wire. The unknown accused entered through the main gate by sawing off the only latch.
“On Sunday night, 18 batteries were stolen. The incidents at the substations are nearly the same. We believe it is an inside job and are making inquiries with railway officials who have worked at the substations,” said Anish Mandal, a divisional security officer with the Railway (Mumbai zone).
A spokesperson for WR said that the batteries were stolen on Sunday night, there was residual electricity in the charger at the substation to provide power to local trains on Monday morning during peak hours.
Mandal added that the unknown accused would have needed a tempo to steal all the batteries as they are heavy. “Sniffer dogs were brought to the spot, however, it had rained and there was no scent of the accused to be picked up. We also did not find any tyre tracks,” Mandal said.
