Jun 2, 2014 (Agencies) : A US robber who stole a woman's iPod and purse was arrested - after he befriended her on Facebook the next day.
The 28-year-old man allegedly hit the woman on the head from behind in the attack at a ferry terminal at Port Orchard, Washington state.
His victim did not recognise the robber but noticed a distinctive tattoo of a triangle on his neck as he ran off with her possessions, reports the Kitsap Sun.
The next day, the woman received a Facebook friend notification and recognised the sender as the man who robbed her.
Investigators quickly tracked down the man via the Facebook account and he has been arrested and charged with robbery.
