A PCSO from Sandwell and three other people have been arrested by West Midlands Police counter-corruption officers investigating information leaks.
The probe was launched after police received intelligence about an information leak and the 42-year-old community officer was arrested at an address in the borough on suspicion of misconduct in a public office yesterday.
Two men aged 57 and 58 were arrested in Blackheath and a 51-year-old woman was arrested in Tipton. They were held on suspicion of procuring misconduct in a public office.
All four have been bailed pending further investigation and the PCSO has been suspended.
Ch Insp Debra Doyle, from the force's Professional Standards Department, said: “We have carried out a large proactive investigation into allegations of leaked information over the last three months which culminated with these four simultaneous arrests yesterday.
“We expect the highest standards from our officers and staff and proactively seek to identify anyone who is suspected of any corrupt activity which would undermine the work of the force.
“The vast majority of West Midlands Police officers and staff are passionate, committed and proud of the work that they do. We have processes and teams in place to ensure that anyone acting suspiciously or suspected of being involved in corruption will be investigated, and where appropriate will be brought before the courts.”
