Police have searched a former massage parlour as they try to piece together how a man received life-threatening injuries before being left for dead in a central Tauranga alley.
Russell William Munday, 49, remains in a critical condition in Waikato Hospital after he was found with serious head injuries on Devonport Rd at 4.50am on Thursday.
Detective Senior Sergeant Greg Turner said police were keeping an open mind about how Mr Munday sustained the injuries.
Police and forensic scientists today completed an examination of a building on Devonport Rd that previously housed Karla's massage parlour and a residential unit where they believe Mr Munday's injuries were sustained.
Detectives were also using CCTV footage to track down possible witnesses.
