>> in the potential new lead in the near 7-year-old disappearance of madeline mcccann.
>> good morning to you.
>> after seven years of searching dead-end leads, scotland yard is making a new plea to the public, this time for another monday who is said to have targeted british tourist and their young girls in portugal.
>> reporter: police say they hope to find a man accused of breaking into vacation homes of british tourists in portugal and sexual live assaulting five young girls between 2004 and 2010 .
>> what about a description of this guy?
>> we know he's spoken english to the children here, had a foreign accent .
>> reporter: they also place him in the resort town where 3-year-old madeline mccann disappeared from her bed without a trace in 2007 .
>> what we can see here is a man who has a very, very unhealthy interest in young, white female children who he's attacking whilst they're in their beds on vacation.
>> reporter: this information is not new. british police condition tend only some of the cases are handed over and the portuguese police didn't see a connection to mccann because there wasn't an abduction.
>> this is a a crime that's captured the public imagination. it's real unusual for scotland yard , british police to come in and investigate an abduction and possible killing abroad and find out what the portuguese police were able to find out.
>> reporter: another potential suspect for investigators and another glimmer of hope for her parents that madeline might one day come home.
>> they firmly believe she's still alive and still out there to be found, as do the british police .
>> reporter: again, scotland yard does not know the identity of this man. they do seem to have quite a detail description, a pot belly , a distinctive smell, tan with messy dark hair. they're hoping this can be the lead that finally solves this case.
