A man who tracked down his stolen iPad using Find My iPhone and a GPS device has been accused of unlawful amateur sleuthing.

Alden Harder, who lives in the Canberra house where the iPad was discovered, is claiming that the man trespassed on his property and committed "trespass via radio wave" when he activated an alarm on the device.

The man's lawyer Keegan Lee dismissed the claims saying: "If he was exercising a claim of right there is no trespass," reports the Camberra Times.

Lee added that ''I would safely say nearly everybody in this courtroom has committed that act [trespass via radio wave] by having a wireless router''.

Having identified the property where his iPad was located, the man went to police but was, he claims, unable to get them to act on the information. He then went back to the house and triggered the alarm, and able to pinpoint the iPad to the garage of the property, went back to the police at which point they obtained a search warrant.
