San Francisco transforms into Gotham City to welcome five-year-old Caped Crusader
The centre of San Francisco transformed into Gotham City - the home of Batman - for a five-year-old boy who celebrated beating cancer by joining his idol, comic book hero Batman, for a day.
ITV News correspondent Nina Nannar reports:
Thousands of fans turned out to watch Miles Scott, now also known as "Bat Kid", whiz around the city with his crime-solving partner Batman - rescuing a damsel in distress from a train track and arresting comic book foe the Riddler at a bank.
Miles, who has battled leukaemia since he was one-year-old and been in remission since June, had his dream fulfilled by the Make a Wish Foundation project.
The mini Batman's heroics didn't go unnoticed from President Barack Obama, who released a short video on the The White House Vine feed, saying, "Way to go Miles, way to save Gotham."
