A 24-year-old woman walking in Frankford early Thursday morning was robbed and sexually assaulted by two men, according to Philadelphia police.
A surveillance camera shot video of the suspects following the victim on bikes in a baseball field on the 4900 block of Ditman Street at 1:30 a.m.
They approached her from behind and one of the men grabbed her by the neck, causing her to lose consciousness, according to investigators.
When the victim woke, she realized her money was missing and she had been sexually assaulted, said police.
Anyone with information about the suspects is asked to call the Special Victims Unit at 215-685-3251.
