A YOUNG woman risked her life after stripping naked and jumping 150 feet (45m) from the Dom Luis I Bridge in Porto.

The female tourist, believed to be Brazilian, was filmed as she made the daring dive head-first into the River Douro.

Thankfully she appeared to be uninjured after the dive

Thankfully the video shows she was okay as she swam back to shore.

The identity of the tourist remains unknown.

Police patrols searched the area after the incident, although found none of the people involved and no arrests have been made so far.

According to local media, the Brazilian tourist had been drinking alcohol before diving into the river.

Hitting water from a height can risk serious injuries, however.

Last year, a 16-year-old woman was left with punctured lungs and six broken ribs after her friend pushed her from a 60 foot bridge.

The woman was jailed for just two days along with 38 days of unpaid work.
