Woolmer case delayed ??

Last CCTV footage shows Woolmer with two men : TOI
This news came few days back. Even kids can see two men in that CCTV footage.
“Some 30 police investigators are working full-time on the Woolmer case”
Wondering that 30 police men did not find the two men in the CCTV footage.
This CCTV footage came out only after the final.
Is the investigation was postponing until the Cricket world cup final 2007 get finish?
If so, it is shameful for the entire world especially the cricket world
