Step by step visual.
1. Try using your state with the keywords Arrest Records, Criminal Arrest Records, Police Records or Jail Records. (Each state has a uniquely setup; be sure to test different keyword variations if you cant locate anything useful).
In this example I used "California Arrest Records"
Oatmeat: There are many places online to search for arrest records. You can search your local county websites to do a search or try to access public court records. Sometimes they are not accessible online and you will have to pay.
Imm: You can use the internet to find arrest records for free. The website http://travel.state.gov/content/passports/english/abroad/legal-matters/criminal-record-check.html will show you arrest records in your state.
ICheck: I think some government websites offer free police records search on their residents, so try finding your state's government website. You may still have to pay some processing fee though. A good idea is to run a background check on the person you want to know police records of, because background check records usually contain all comprehensive records including police arrest records.
Isabel: Even if you try to obtain them from the government source directly, they charge you a fee in order to do that. There are some cheap resources that do this in bulk and provide this for a cheaper rate so you might want to give them a go.
Paul: For anyone that simply really needs localized records and is also prepared to look around; a restricted free background check may be possible. It may help much to be google search savvy.
Mikey: Try this site http://mugshots.louisvilleky.gov/archonixxjailsiteslmdc/archonixxjailpublic/ if you're in Louisville. Hope this helps.
Bart: There is no absolutely free records look up. You should use a legit service for your lookup
