US police investigating a murder have tussled with Amazon over access to data gathered by one of its Echo speakers.
The voice-controlled device was found near to a hot tub where the victim was found dead amid signs of a struggle.
According to court filings, Amazon was issued with two search warrants but refused to share information sent by the smart device to its servers.
However, the police said a detective found a way to extract some data from the device itself.
