Why Are the Police Wanting Me to Come to Their Station

[Narelle]

My question involves criminal law for the state of: Western Australia
Hi, two weeks ago I went into best and less and took 3 items to the value of $75. The shop assistant and security officer stopped me ten minutes later in front of another store with my children. I have been placed on heavy medication for depression following a divorce and have even experiencing financial hardship. They said they saw me on security camera putting something black in my bag. After they went through all my shopping the found all three items and took them back, informed me I was banned from the whole shopping centre for six months and i was escorted out by the security guard. However the police have been at my parents house and my house looking for me and left a card so I rang them and they informed me I need to go down to their station to discuss what happened. They said all officers around wa have my name and if I don't come down to get it sorted and get stopped driving I will be arrested. I have all my kids with me and do not know what to expect at the station and am very scared. Can you let me know what will happen as I thought it was dealt with on the day by the shop workers.
Regards

This is primarily a US website; the laws of Australia and the laws of the US are not the same. I don't believe we have any experts in Australian law here.

Still, it's reasonably safe to say "Because you committed a crime, you are under investigation for your criminal activity, and the police hope that you will confess to your crime."
