Two men are due to appear before a court charged with murder this morning following a disturbance at a block of flats which claimed the life of a 39-year-old man.
The pair, aged 31 and 36, will face the allegation at Teesside Magistrates' Court.
Officers found a seriously injured man, who died a short time later.
A number of men and women were arrested during the weekend in connection with the death and have been released as the investigation continues.
Mr Gilling's family have paid tributes to him through the force, which says they have been left "heartbroken" by their loss.
His loved ones said: "We have been left utterly saddened and shocked by Peter’s death.
"He was a much loved son, brother and grandson and he will be hugely missed by all his family and by his many friends.
“We hope his death will not be in vain and that no other family has to endure the devastation and heartache we are currently going through - and will continue to go through.
“As a family we would now ask to be left to grieve in peace.”
