The boyfriend of slain Christchurch sex worker Renee Duckmanton is under investigation by police, for allegedly withdrawing money from her bank account after her death.
More than $1000 was reportedly transferred out of her account.
Police say it is not clear at this point whether Ms Duckmanton's partner was directly involved.
The 22-year-old's body was found near Rakaia River in May and a man was later charged with her murder.
He is due in the High Court in August.
