Nelson police have spent much of today canvassing a neighbourhood where a 62-year-old woman was beaten and sexually assaulted as she worked alone at a community garden.
Police are hunting the "cowardly'' attacker and urged locals in the Victory area of Nelson to take safety precautions until he was in custody.
The woman was working alone in a shade house at the Victory community gardens about 2.30pm when she was attacked by a man believed to be aged in his 20s.
This evening, she remained in hospital with substantial head and facial injuries, along with other lacerations and bruising to her body. Her injuries were not life-threatening.
Detective Sergeant Ian Langridge of Nelson CIB said police had serious concerns about the behaviour of the offender and what he might be capable of.
