There was considerable helicopter noise around Stockwell last night, which is explained by the reports that two men were stabbed in Larkhall Park. A teenage boy has died. One other male is injured.
The police/media don't seem to have reported many details yet. Stockwell news quotes The Evening Standard, which suggests that the stabbings were part of local gang violence. The BBC have a report which offers little extra detail, along with a video of the taped off area that must have been shot last night. The Press Association say that four men are being held in connection with the stabbing.
The stabbing is some way outside the SE11 patch in SW8, but I've had various google queries here this morning from people looking for information.
