A SELF-proclaimed spy terrorised her neighbours by playing the Laughing Policeman 24 hours a day — in a row over a hedge.
Susan Chen, who claims she was a Chinese Army intelligence officer for 14 years, flipped when her privet was trimmed by a well-meaning family.
She set up cameras, spied on the entire street, shone torches through windows, rattled paint tins of stones and knocked on doors in the middle of the night.
Chen, 61, also played the Laughing Policeman’s creepy cackle on loop in Bassingham, Lincs.
But her antics landed her and daughter Linda Lu, 35, behind bars as they were convicted of stalking.
They were remanded in custody to be sentenced in December at Lincoln crown court.
One local told The Sun: “ You get neighbour rows over hedges – but not usually when one is a Chinese spy.
“The Smiths were just trying to be neighbourly, they always looked after the hedge and most people would be grateful.
“But Chen just went crazy – and started using military tactics against them. It was unbelievable.
“She put the whole street under surveillance so she knew what all their ‘moves’ were. Any training she had must have kicked-in.
“They had cameras set-up but would also manually spy on everyone.
“If there was anyone out for a walk they would watch them all the way past their house.
“Then there was the harassment of all their neighbours – it was psychological warfare against everyone.
