The 21-year-old footballer said the group of robbers broke into his house on Tuesday and snatched a safe containing his Champions League, Super Cup, and Euro 2020 medals.
James shared a number of CCTV clips of the shocking burglary, showing four suspects walking up the driveway of his home and shining torches into the house.
One video shows the group struggling to open the electric gates to the property as they lift a huge safe out of the house and roll it across the driveway.
The Chelsea defender shared the clips outside his home as he appealed for fans to help “identify and turn in these low life individuals”.
He added: “I hope together we can catch these individuals and deliver justice where it is due.”
