Officers have released an image of a man they wish to trace after an altercation at Woodthorpe Grange Park.
The incident happened at around 10.37am on Tuesday 20 February.
A 61-year-old man was walking in the park when he noticed a man shouting at a woman near the playground.
The man then approached the 61-year-old and hurled abuse at him. He later saw the suspect at the top of the alleyway near Woodthorpe Grange, Nottingham.
The suspect has then threatened, spat and pushed the victim, before leaving the area.
Officers have carried out a CCTV trawl of the park and attempted to piece together what has happened by speaking to other park users.
They have now released an image of a man that could help them with their inquiries.

PC Harry Ford, who is investigating the incident, said:
“It is completely unacceptable for someone to be spat at and pushed while they are out enjoying the park.
“We have already carried out a number of lines of inquiry. We have now released an image of a man that could help us with our investigation and we would urge the public to contact us if they recognise him.
“If you know the person or you are the person in the image, please get in touch as soon as possible.”
Anyone with information should call 101 quoting incident number 0194 of the 20 February 2024 or Crimestoppers anonymously on 0800 555 111.
