More than 300 criminal cases in Cleveland and Staffordshire that were potentially botched by a scenes of crime officer accused of lying about his qualifications are being reviewed by the police watchdog.
Stephen Beattie, 49, first came under scrutiny in 2011 for his work for Cleveland and Staffordshire police and the Independent Police Complaints Commission (IPCC) has now revealed that 355 of his cases are being looked at again.
In August last year it said that 90 cases involving suspicious deaths were being re-examined, but this has risen to 141. Another 214 arson investigations are also being reviewed.
"This remains a complex investigation covering a period of 15 years and a significant number of cases.
"The examination of those cases is ongoing but is a huge task and will take several more months.
"The most significant cases have been prioritised and any additional work identified has been acted on immediately. Cleveland Police have ensured that families affected by these cases have been kept informed."
