"We believe this may have been an opportunistic attack and is a timely reminder to everyone to keep their houses secure at night and be mindful of strangers in their neighbourhood.
"We are very keen to speak to anyone who saw a person acting suspiciously in the Logan Ave area last night. Someone may have seen this man walking along the street or perhaps in nearby streets," Mr Alexander said.
A police statement today described the man as "part-Maori in his 30s, of stocky build with short dark hair. He was wearing a dark-coloured hoodie and pants and fingerless gloves. He was about 1.7m tall."
Anyone with information about the man should contact Mr Alexander at HB Police on 06 8310806 or information can be left anonymously on Crimestoppers 0800 555 111.
