Police are investigating how a Feilding woman received ''unexplained'' injuries that left her in a critical condition in Palmerston North hospital.
Emergency services were called to a Russell St, Feilding address about 8.30pm last night where they found a 49-year-old woman in need of medical treatment.
One of three flats was under police guard this morning, and police officers were knocking on the doors of nearby properties.
Tanya Pawson, who lives near the flats, said she didn't hear anything last night other than fire engines and an ambulance arriving.
There was a fire at another property on Russell St about 7pm that evening, and the strong smell of burning rubber was in the air, she said.
The fire service were called to the flats about 8.40pm and blocked off the road on either side.
She did not see police at the house last night, but a police car was on guard at the flats when she woke up at 5am, she said.
She believed a couple had moved into the flat a few months ago, and had a small dog.
It was ''the first time in a long time'' they'd seen such events in the street, which was usually very quiet, she said.
Detective Senior Sergeant Craig Sheridan, officer in charge of the Manawatu CIB, said 18 police officers and two staff from ESR were investigating.
''Our priority is to determine how the woman has sustained her injuries. At this stage I am not prepared to comment on the extent of her injuries except to say they are critical and unexplained,'' Sheridan said.
''We will also be speaking to the woman's partner, family, and friends over the coming days to piece together her movements prior to her being admitted to hospital.''
A scene examination is underway at the woman's Feilding property and was expected to be completed in the next 48 hours.
''At this stage we are not sure what we are dealing with and we don't have a lot of details. It's likely to take some time to piece together the circumstances however we are focused on conducting a thorough investigation and hope to have a clearer picture of how the woman has sustained her injuries from our inquiries,'' Sheridan said.
