A witness to a teenager attempting suicide twice in one day in Christchurch is calling for an investigation.
Hannah Carter and her partner were driving over the Wrights Road overpass on Sunday when they saw a woman standing on the bridge.
Her partner Elliot Sizer ran up the bank while she called emergency services.
He spoke with the teen then grabbed her and pulled her back as she got closer to the edge.
Carter says the distressed woman told them she was 19-years-old and had deep self-inflicted cuts on her arms.
She says police arrived and took the teen to Hillmorton hospital.
"Two hours later, I drove down that same road and noticed that there was a handful of cars and cops behind us, and I looked behind me and there she was again, up on the bridge."
Carter says she's shocked the woman who clearly needed help was released from the hospital so soon.
"She's a girl, who's screaming out for help and she's been taken to the one place where she is supposed to receive that, and she's just been turned away."
She says it's ridiculous the hospital released the teenage within a couple of hours.
Carter says she hopes Hillmorton Hospital investigate what happened.
"And put the processes in place to ensure it doesn't happen again."
In a statement to NewstalkZB, a spokesperson for the CDHB says whenever there is a significant event or near-miss, staff review what happened, the circumstances at the time of the event and what, if anything, could be done to prevent a similar event happening in the future.
It says they're unable to comment on individual cases due to privacy reasons.
