A masked gang on mopeds, scramblers and quad bikes tore through a popular picnic spot yesterday afternoon narrowly missing families enjoying the sun.
In one clip, one of the bikers did a huge wheelie, just yards from youngsters playing a game of frisbee.
The footage was recorded at Cannon Hill Park in Birmingham on Sunday and a shows men, women and children looking on in horror as the group ride around the Edgbaston park.
Sendijs Petrovs, who visits regularly with his daughter, tweeted the video to West Midlands Police in a bid to prevent such incidents happening again.
He asked: "There's kids playing here and this gang is just ploughing through the park - What can you do about this?"
He told BirminghamLive the gang arrived just before 5pm before speeding around the park.
