German prosecutors probing an Algarve rape linked to Madeleine McCann suspect Christian Brueckner have been handed a sketch of a 'distinctive' mark on a sex attacker's right leg.
An Irish mother-of-two has described a man with a German accent and piercing blue eyes attacking her in Praia da Rocha, a half-hour drive from Praia da Luz where Madeleine vanished.
The cross-shaped image, drawn by the victim, was sent to German authorities after she asked detectives investigating the toddler's disappearance to review her case.
Case files which Portuguese prosecutors have made available also include her sketches of the machete-style knife and whip used by her masked rapist, along with descriptions of his rucksack and a camera he filmed the horrific sex attack with.

Braunschweig-based prosecutor Hans Christian Wolters confirmed earlier this week he had re-opened an investigation into the June 2004 rape.
The victim asked detectives probing Madeleine's disappearance to review her case in June after discovering Brueckner had been convicted last year in Germany of the August 2005 rape of an American OAP in Praia da Luz.
She told police her masked attacker spoke English with a German accent and had piercing blue eyes like the 43-year-old drifter being probed over Madeleine's disappearance.
And she also recalled a mark on top of his right thigh, describing it as a 'pull in the tights, a birthmark or a tattoo' in an interview about the attack in Praia da Rocha.
Brueckner, convicted of the 2005 rape through a hair found at the crime scene which Portuguese investigators had failed to test, is said to have birthmarks on his upper right thigh.
Portuguese court files make it clear DNA was obtained but no match was made at the time.
The DNA samples including blood and semen collected from the crime scene by Portuguese police were later destroyed on the orders of prosecutors, leaving question marks over whether a successful prosecution can ever be mounted.
Portuguese authorities agreed to hand over the archive material, and new police statements the Irish rape victim made to Gardai in June which were forwarded to them, following an official German request for cooperation.
The request reached the court in the Algarve town of Portimao which is probing Madeleine McCann's disappearance on August 24.
Prosecutor Joana Ribeiro Garcia sent the case files to German authorities on September 9.
