Binge drinking and a youth knife culture have been blamed for a rise in violent crime in "one of the most testing" years for West Midlands Police.
Despite overall recorded crime in the region falling to its lowest for almost decade, key targets on reducing domestic burglary and robbery were also missed and there was a substantial increase in drugs offences and public order offences.
In in its annual report presented at its meeting yesterday, West Midlands Police Authority said overall crime in 2005/06 had dropped by two per cent, to 288,055 incidents, compared with the previous year.
However, violent crime rose by 2.6 per cent, to 69,337 offences, largely due to the increase in public order offences which went up by almost a fifth. Mr Scott-Lee had targeted a five per cent reduction in violent crime.
The force highlighted its Operation Safer Nights campaign cracking down on binge drinking and a spokesman said a "zero tolerance" approach to drunken trouble-makers had led to more arrests for violent crime.
"We are doing more to proactively target these alcohol-related offences before they escalate into more serious issues," said Chief Constable Paul Scott-Lee.
Authority chairman Diana Holl-Allen said it was too early to blame the increase in public order offences on new licensing laws allowing pubs and clubs to stay open later.
Instead, she highlighted her concerns over a growing trend of young people carrying knives.
"A good number of young people seem to carry knives around in so-called self-defence," she said.
"We are trying very hard to tackle this.
"It worries me that there are those in the community that want to take up seriously dangerous objects in their hands.
"These knives are a problem."
Crimes committed by young people were a major factor in many of the more serious offences.
The overall detection rate was 26.1 per cent - 75,053 offences - and almost a quarter of these detections were attributed to juveniles.
The growth in juvenile robberies was largely fuelled by children stealing mobile phones and MP3 players, according to police, but wounding was the single biggest area of detected crime among youngsters with more than 3,600 incidents.
The force defended failures to meet targets of reducing robberies and domestic burglary by five per cent.
The actual figures were a 0.3 per cent and 2.6 per cent reduction respectively.
"These were ambitious targets," said the spokesman.
"There has been significant reduction in robberies since 2001 and with domestic burglary this year's reduction is not insignificant."
Drug offences were on the rise in the region with trafficking of heroin and cocaine up by 28.6 per cent; possession of other class A drugs up 23.9 per cent and other drug offences such as possession of cannabis up 30 per cent.
The force blamed the increase on a "proactive" policing approach that included large scale drug busts in Birmingham, Coventry and Wolverhampton.
Murder was down more than a quarter in the region, to 45 offences during the year; attempted murder reduced by 13.8 per cent to 50 and vehicle theft fell by 14.9 per cent.
There were 1,553 incidents of racial or religious aggravated harassment and 1,201 of cruelty to children.
On the roads, there was an increase in drink driving with 5,243 people stopped.
