Further details of Prince's final hours have been revealed, although the post-mortem results have yet to draw a conclusive result on his death.

However, Minnesotan police have confirmed that the singer - who died a week ago today - was found with prescription painkillers in his possession and at his house.

The find tallies with unconfirmed reports that he had been hospitalised for an overdose of Percocet - the same painkiller that killed Michael Jackson - the Friday before he passed away.

Officials in Carver County, Minnesota said that they were working with the Drug Enforcement Agency to determine where the prescription had come from, although this is a routine check in such circumstances.

Rumours that the music icon was taking the painkillers for problems with his hip, which had been damaged after years of performing, were unfounded.

In any case, toxicology reports could take weeks to come through, so it's all speculation until then.
