I answered on my cell. Took a couple of seconds for the computer to click over. Some guy started talking while I was hanging up. I called the number back from my work phone. A generic "all our representatives are busy at this time" recording came on, then (what sounded like the same guy) just said "hello" (rather than, "thank you for calling blah blah blah", or some other business type greeting one would get when calling a place of business). Hung up again. According to all the comments above, looks like a scam, and the number is now blocked!
this number is a scam. a citizen just reported it to my station. NEVER make donations to any police organization that calls or visits you. any questions, please call me at LAPD Mission Division, 818 838 9461.
