Reign of terror continues against trotting family

A REIGN of terror targeting South Australia's Johnson family has continued overnight.

In the seventh of a series of attacks, graffiti was sprayed around Globe Derby racetrack, with the profanity covering approximately 250 metres of fencing, with Lane Johnson the focus of the vandalism.

Scheduled to conduct a meeting this afternoon, with the first race to begin at 1:53, the Globe Derby club was covering the graffiti with plastic as this article was being written.

Only weeks ago Lane's son, Corey's Holden Colorado was set alight in the Globe Derby carpark while the young reinsman was driving in race four.

A suspect was seen talking on a phone while circling the parking area on an e-bike before dousing Johnson's vehicle in petrol and setting it ablaze.

It's the second Johnson car to be set alight, with the other - a Holden Commodore - falling victim to a molotov cocktail at the family home in January.

Last December, another molotov cocktail was thrown over the property's fence.

The incidents also include dumping of oil, hardware items and broken glass on the Johnson's training track and graffiti.

Harness Racing SA stewards released a statement on January 15 calling for "information in relation to a disturbing and escalating campaign of criminal conduct directed at the Johnson Stables.

"These acts are criminal, deliberate, and dangerous. They pose a serious threat to the safety of people, horses, and property.

"This behaviour goes well beyond nuisance vandalism - it is reckless, malicious, and intolerable."

As with the previous incidents, Police are investigating the matter.
