James Dobson, from Morecambe, had last been seen on November 25 outside the Magistrates' Court in Lawson Street, Preston.
Lancashire Police issued an appeal to find James and said they were growing 'increasingly concerned' for the 17-year-old's welfare.
But police have confirmed that James was found 'safe and well' yesterday (January 2).
"We can now let you know that he was found safe and well this lunchtime, Thursday, January 2.
"Thank you to everybody who shared our appeal."
