Four-year-old child found dead in Brisbane

Police have declared a crime scene in Brisbane's east after a four-year-old child was found dead.

Emergency services were called to the home on Bent Street in Cannon Hill about 9.30am.

Police have cordoned off Bent Street and detectives are trying to determine the cause of death.

About 10 police cars and two ambulances were at the home, which is near Cannon Hill Anglican College.

A neighbour, who did not wish to be named, said she and her husband heard many sirens going down their street early Monday morning.

She later walked down Bent Street to get a coffee and saw police cars and officers talking to a woman, who was holding a younger child, at the house.

According to property data, the house involved is a rental.

The school sent an email to parents advising them that the street would remain closed for the rest of the day, and that alternative arrangements for school pick-up were being made.

"This morning an incident occurred in a residence in Bent Street close to CHAC Primary," the email read.

"Should you hear of this incident through the media, please be assured that there is no reason to be fearful of any threat to the school and your children are safe and are being kept totally unaware of the police presence outside the college.

"We are currently working with the police on a plan for pick up at the end of the day. Please continue to monitor your emails for updates."
