The phone was rang, i saw this weird # 520-555-5555 on the screen. I did not get it.
minutes later, Tucson police showed at the door. They said they just received 911 call from me. they asked if i need help ? Sure i am OK?..
This weird!!

BOGUS CALL. DO  NOT ANSWER

This number a number used by the TPD call center.  I received  a call from that number, then a TPD Officer called to find out if everything was OK.  Called 911 to check, they confirmed that this a a number used by them when they receive a 911 call which they are trying to verify.  Someone called TPD gave our number and said there was an emergency at our home. However, the 555-5555 is not a number which can be called back.

I got a cal from 520-555-5555, they said my phone had dialed 911 and asked if I was ok.  I told them I didnt dial 911 and I was ok, and they hung up. sounds like a scam thing to me.
