The demolition of a disused building at Grain Power Station is believed to be the cause of a explosive noise on Sheppey this morning.

It is understood energy company E.ON notified local residents of its intention to carry out its destruction at 8am, which is when a loud, thunderous sound was reported by Island residents.

At first, it was thought the 650ft chimney stack at Kingsnorth Power Station, which overlooks Sheppey and is in the process of being taken down, had been demolished.

But it's not due to disappear completely until 2016.

Grain-A power station was closed in 2012, and Kingsnorth a year later because it did not meet EU standards on pollution.

Energy firm E.ON announced last year that work had started to knock both plants down.

Police said they had not received any calls from residents about this morning's explosive noise.
