So far:
Alves has changed his statement several times, initially claiming he didn't know who she was, then claiming they had consensual sexual relations together, then claiming it was her who forced him on top of her and not him.
The woman for her part has allegedly given a very consistent and coherent statement and not changed anything she said. She has also rejected the possibility of taking any financial compensation as she wants justice for what she claims he has done.
CCTV footage proves that Alves lied in his initial statements and that he did go into the toilet she was in, traces of semen were found in the same toilet, whilst fingerprints were also found confirming their presence there. The woman also went to hospital a few days after the attack for an examination where injuries consistent with forced penetration were noted. Witnesses at the disco also apparently back up her story but it is not clear how currently. For all these reasons the Catalan police have considered her statement highly credible.
Also, the duration of which they were in the toilet was 16 minutes, 47 seconds was the difference between the time they left.
Unfortunately this case seems pretty cut and dry. There is very solid proof that he followed her into the toilet, traces of semen were found inside it, she is examined days later and confirmed to have injuries related to **** attack, Alves has changed his version of events three times whilst she has had the same story throughout and been as cooperative as possible with police.
