Portsmouth Teenager Arrested Over Deadly Fire
Detectives investigating a fire, which killed six members of the same family, have made two arrests - including a man from Portsmouth.
Doctor Abdul Shakoor was the only survivor of the blaze at the family's home in Barn Mead in Harlow, Essex last October.
Police launched a murder investigation after his wife, Sabah Usmani, and their children, Muneeb, nine, Rayyan, six, Hira, 12, Sohaib, 11, and Maheen, three, all died.
Essex Police said the Portsmouth man, 19, and a 19-year-old man from Harlow, had been arrested and questioned in connection to the fire and a burglary which happened shortly before. They've been released on bail.
Another 19-year-old man, also from Harlow, remains on bail after being arrested on an earlier date.
Violent crime was up 37% in the last year. Police say it's mainly due to a change in how offences are recorded.
