Crimestoppers Most Wanted gallery has featured more than 12,500 appeals since its launch in 2005.
There have been 3,589 arrests from the 12,524 appeals made on the site, which allows members of the public to give anonymous tips about suspects.
It was the first national online source of wanted individuals across the UK for crimes including murder, sexual assault and burglary.
Gemma Wilson, Yorkshire and Humberside regional manager for Crimestoppers, said: “Most Wanted appeals to the nation’s ‘arm chair’ detectives – those who want to help fight crime from the safety of their own home and, above all else, anonymously.
“It was quite ground-breaking when it first launched as the first national online source of wanted individuals and it continues to be an important tool.”
