SAN FRANCISCO (AP) -- Batkid is fighting crime on the mean streets of San Francisco.
Television news footage showed 5-year-old Miles Scott, aka Batkid, leaving the city's Union Square in one of two Batmobiles on Friday morning. The vehicles -- two black Lamborghinis with Batman decals -- were surrounded by media and onlookers.
By midday, the Batkid's adventure had become a sensation on Twitter, with even the White House chiming in with its support.

The Lamborghinis were escorted by police, who also blocked off roads. Batkid's first caper was rescuing a damsel in distress from cable car tracks. He was also scheduled to capture the Riddler as he robs a downtown bank and receive a key to the city from Mayor Ed Lee.
The drive through city streets is part of a day of events organized by the Make-A-Wish Foundation to fulfill Miles' wish to be Batkid. Miles was diagnosed with leukemia and is in remission.
Miles, who lives in Tulelake in far Northern California, didn't know what was in store for him and thought he was in San Francisco just to get a Batman costume so he could dress like his favorite superhero, KGO-TV reported.
He was diagnosed with leukemia when he was 18 months old and ended treatments in June.
His father, Nick Scott, thanked the Greater Bay Area Make-A-Wish Foundation and the estimated 7,000 people who will help make his son's wish come true.
"All the doctors, nurses and all the other parents that have to deal with the same thing we're going through. I hope they get a conclusion to their illnesses like we're getting," Nick Scott told KGO-TV.
