Det. Chief Insp. Marie Haworth, of East CID, said: “The victim of this assault remains in a very serious condition in hospital and our enquiries are on-going.
“The motive for this assault remains unclear at this stage but we have a team of detectives and uniformed officers and staff working hard to identify those responsible.
"We are carrying out house to house enquiries in the area and checking CCTV but we also need the public’s help and I would appeal to anyone who saw anything suspicious on Friday evening, or in the lead up to this incident, to get in touch.
“Incidents like this are extremely rare but as an extra precaution I would advise people to be careful when opening the door, especially at night, to ensure you know who is there when you answer.”
Anyone with information should contact 101 quoting log number 1192 of December 1st.
