I am a CPS teacher and on Wednesday morning I was attending the CPS Board of Education meeting with my former student Zaid Khan, who was speaking to the board in person during public participation. I arrived first and locked my bicycle around 9:20 am with an ABUS Bordo lock to the bike rack at 42 W Madison, next to the CTA bus stop and to the corner camera of the Chicago Public Schools. I went to the Dunkin Donuts down the street for coffee when Zaid arrived around 9:35 am and returned around 10:20 am and the bike was still there. We entered CPS to attend the Board meeting at 10:30 am. I left shortly after 1 pm and the bike was gone. I talked to the security guard at CPS and he showed me the camera footage. It should have been between 12 and 1 pm, when some construction workers were standing next to the bike rack by the bus stop. A middle-aged, around 5' 11''tall, slim, African-American male approached the bike and opened the lock. Then, he took the lock and rode the bike down Madison street towards the west. I asked the security guard if there was any way that I could get the camera footage, because everything was caught on their camera and it could be possible to identify the thief, but he said it was not possible. I wanted to use the footage to file the report and provide it as evidence to the police. I would like to ask CPD to request the footage from CPS.
