Detectives investigating a shooting incident in Cranham in which a child was injured continue to appeal for information.
Two males A -16yrs and B – 18yrs were arrested on suspicion of aggravated burglary and taken into police custody.
A was bailed to return on a date in late May, pending further enquiries.
B has been released with no further action, on Monday afternoon May 4.
A dedicated team of officers from the Specialist Crime Command are carrying out various enquiries in relation to the incident.
Police were called at 21:30hrs on Friday, 1 May, to an address on Kerry Drive in Upminster.
Officers attended along with the London Ambulance Service (LAS) and found two people at the address suffering injuries.
A boy, aged around 11 years old, had sustained a gunshot injury.
A man, believed to be aged in his 40s, had sustained lacerations to his head. At this stage it is unknown whether his injuries were caused by the firearm discharge or a knife.
Both were injured inside the address.
They were taken to hospital by the LAS. The condition of the man has been assessed as not life-threatening or life-changing.
The condition of the boy has been assessed as not life-threatening but may be life-changing. He remains in hospital in a serious but stable condition.
A number of suspects had made off prior to the arrival of police.
Detectives have established that the homeowner opened the front door to a person purporting to be a delivery driver; this male, and a number of other suspects – believed to be in possession of a knife – forced their way into the property.
Two firearms were recovered from the address. Work continues to establish the full circumstances.
Detective Inspector Matt Webb, from the Met’s Specialist Crime Command, said: “This nightmarish attack on the victims’ own doorstep has, understandably, shaken the family and the local community.
“I want to reassure them that we are pursuing this case and trawling through potential leads and evidence. I am asking the public to help us track down those who committed this crime. If you have any information, no matter how small or insignificant you think it might be, please get in touch.
“We will work tirelessly to identify and pursue offenders, help bring perpetrators to justice, take weapons off the street, support victims, engage and reassure the public, and keep our communities safe.”
Any witnesses are asked to call police on 101 quoting reference 7285/01May. To remain anonymous, please contact the independent charity Crimestoppers.
Residents can expect to see an increased police presence in the area as part of reassurance patrols over the weekend and are encouraged to approach officers to speak about any concerns.
