Birmingham needle attacks: Police 'unable to proceed'
No charges are to be brought in connection with a series of needle attacks in Birmingham because of "insufficient evidence", police said.
Officers launched an investigation after a 30-year-old woman suffered a puncture wound in November. They also considered 10 other incidents they said could be linked to the same attacker.
Two men, aged 29 and 30, from the Smethwick area, were arrested.
But Det Insp Tom Chisholm said they had been unable to charge anyone.
'No further attacks'
"The investigation into the syringe attacks in Birmingham was large-scale and wide-ranging," he said.
"Detectives gathered a large amount of evidence and worked closely with CPS.
"Unfortunately, due to the nature of many of the offences, there was insufficient evidence to proceed at this time.
"Since the arrest in November no further attacks have been reported."
