what short memories some people have:
Redwood "These offences are very serious and no one has been charged in connection with them. We also need to eliminate this man from our inquiries and ascertain whether these offences are linked to Madeleine's disappearance," he said.
"If you have been a victim of a similar crime please come forward even if you reported the incident to police in Portugal, or anywhere else, please do not assume we have been made aware of it."
There was also a "very close resonance" to some features of Madeleine's disappearance, said Redwood.
"We really need to identify the offender, to bring to a close the trauma and the tragedy that these families have suffered, and then seek to establish whether this is connected to Madeleine's disappearance."
Also, from the same article, this (which will no doubt be scoffed at as the source is not named):
Scotland Yard also revealed it was looking at 38 "people of interest" in relation to her disappearance, having dismissed 22 others from that category. They were also trying to find out more about 530 known sex offenders – 59 regarded as of high interest – across Europe.
However Portugal's Polícia Judiciária (PJ) claimed that Wednesday's press conference simply confirmed a primary line of investigation which has been investigated by Portuguese police since last October. Suggestions that the information released by the Met had initially been discounted by Portuguese detectives were denied by a source at the PJ's headquarters in Lisbon.
He said that evidence of a string of crimes had been the driving force behind Portuguese officials re-opening the case. "It is all there in the police case files," said the source. "You will see when it is made public."
