A suspect package alert at HMS Nelson today was caused by a ‘small explosion’, police say.
Police and other emergency services have now been stood down from the Portsmouth navy base after reports of a suspicious package.
A faulty battery, found next to some empty packaging, caused a small explosion.
A female naval rating received minor burns to her arms and was treated at the scene.
HMS Nelson was not evacuated.
The call was received at around 10am today.
Police say there is no evidence to suggest a risk to the public or any kind of crime or threat to HMS Nelson.

Police said that the base had not been sealed off and military personnel, workers and visitors were still able to go in and out. No roads in the area were closed.
At the gates of HMS Nelson, two fire engines could be seen and several unmarked cars with blue lights on.
