A man from Treharris sparked a dramatic police chase through the outskirts of Cardiff after throwing packets of cocaine out of his car window along a busy main road. The incident, which unfolded in daylight, put motorists and police at risk and later uncovered the extent of his involvement in drug production and supply.
James Grapper, whose previous criminal record includes a series of drug offences, was at the centre of this high-octane pursuit. The trouble began when officers noticed a car behaving suspiciously and erratically on the M4 near Cardiff on 26 May this year. Routine checks revealed the vehicle was registered to Grapper, who was already barred from driving due to past convictions.
Rather than pulling over when requested, Grapper accelerated sharply after taking the exit onto the A470 northbound. This prompted police to authorise a full pursuit, during which Grapper reached estimated speeds of up to 100 miles per hour. Officers witnessed him flinging small packages out of his vehicle window as he sped past other motorists, raising concerns not just about his disregard for public safety but also suggesting attempts to discard incriminating evidence.
The chase soon became more intense, with police forced to use a “stinger” device in an attempt to puncture Grapper’s tyres and slow the vehicle. One tyre was deflated, but this did little to deter Grapper who continued to drive at high speed on the metal rims, weaving between vehicles and performing dangerous manoeuvres to evade capture.
Eventually, police succeeded in boxing in his car after a second manoeuvre, forcibly bringing the episode to a halt. Despite being surrounded, Grapper rammed a police vehicle in a further failed attempt to escape. Once apprehended, officers administered a roadside breath test which showed he was over twice the legal alcohol limit. Grapper then refused to provide a further breath sample for formal analysis, compounding the charges against him.
Subsequent investigation revealed the gravity of Grapper’s criminal undertakings. Officers retrieved the discarded packets from along the chase route, which were confirmed to contain cocaine. A search of his home unearthed further illegal substances and weapons, including a knuckle duster and a bladed item resembling a sword. The most significant find was a sophisticated cannabis grow operation occupying the attic, where 14 mature plants and 45 younger specimens were being cultivated, alongside quantities of harvested cannabis.
Analysis of Grapper’s phone provided additional evidence of active drug dealing, with communications indicating ongoing supply of both cocaine and cannabis. Given his record—including prior convictions for drug production and drug driving—the case against him rapidly mounted.
At Cardiff Crown Court, Grapper admitted a raft of offences: dangerous driving, driving while disqualified, lack of insurance, failing to provide a specimen, possession of cocaine and cannabis with intent to supply, and possession of offensive weapons and bladed articles. With 21 previous convictions for 35 offences, the scale of Grapper’s criminal history became an important factor in sentencing.
Representing Grapper, his barrister Sol Hartley highlighted the defendant’s troubled upbringing, referencing the absence of a father-figure and Grapper’s stated wish to provide better for his own children. While the court acknowledged these mitigating circumstances, the severity and danger of Grapper’s actions demanded a custodial sentence.
Grapper was handed a total sentence of 54 months’ imprisonment, with a requirement to serve at least half before being considered for release on licence. Additionally, he was banned from driving for over four years and must complete an extended retest should he seek to regain his licence in the future.
This case shines a spotlight on the ongoing efforts of South Wales Police to tackle drug-related crime and the associated risks to communities. It is a reminder of the dangers posed when individuals with prior convictions attempt to evade the law, putting both the public and officers in perilous situations.
