A man was punched in the face when he refused to hand over a hammer after intervening in an argument, magistrates have heard.
Sean Flanagan, 26, of Bagge Road, Gaywood, pleaded guilty to charges of assault and obstructing or resisting a police officer during a hearing on Wednesday.
The court heard the incident had taken place in Lynn on November 8.
Paul Brown, prosecuting, said the assault victim had done “quite a courageous thing” to intervene in a dispute involving a couple when he saw the woman had a hammer.
He managed to grab the weapon before being approached by Flanagan and another man, who demanded he hand it over to them. When he refused, Flanagan punched him, causing soreness to the jaw.
The court heard Flanagan then barricaded himself inside a house and threatened to harm himself.
Flanagan was bailed until January 22 for pre-sentence reports to be prepared.
