Andrew Toseland assault: Officer given written warning
A police officer has received a written warning following an investigation into how his force handled events before a man was attacked outside his flat.
Andrew Toseland suffered serious brain injuries in the assault by a group of men in Gosport in August 2012.
The Independent Police Complaints Commission (IPCC) found Insp Jim Logan had a case to answer for misconduct.
Hampshire Police said it accepted the IPCC's final report and has acted upon its conclusions thoroughly.
The IPCC concluded Mr Logan, then a police sergeant, did not "sufficiently grasp the issues" of anti-social behaviour leading up to the attack.
Mr Toseland, 51, was left in a coma after he was stamped on outside his home in Garland Court. Two men were jailed for their part in the attack.
Mr Logan appeared before a misconduct meeting earlier this month when the case against him was proven.
The IPCC investigation, which concluded in September, found he "breached the standards of professional behaviour expected by inadequately supervising local officers".
Commissioner Derrick Campbell said: "Such failings are a clear breach of the standards expected of officers and it is right Insp Logan has received a written warning."
Hampshire Police regretted any upset or distress the events had caused to relatives of Mr Toseland and other residents.
A spokesman said: "We recognise our service to the residents of Garland Court in 2012 did not meet the standard of excellence expected by this force.
"We chose to refer this matter to the IPCC voluntarily in 2012 because the force wants to be open and transparent in how it is held accountable for its actions."
