A city centre was placed in lockdown after a man believed to be naked and wrapped in a blanket climbed on to the roof of a train station.

The man, covered in blood, refused to climb down from a window sill on the roof of Perth Train Station in Wellington Street despite attempts from police.

It is understood negotiations had been ongoing since the man, who is known to police, first climbed the station at 6am on Saturday.

'Police are currently at the Perth Train Station trying to negotiate with a male person who has climbed on to the roof of the railway station and refusing to get down,' a spokesperson for police said at the time.

The man was eventually convinced to come back inside the building and was given clothes by police before he was taken to hospital with cuts on his body.

Sections of Wellington street were closed during negotiations and have now been reopened.
