An angry Sutton Bridge man was foaming at the mouth as he chased his partner down the street with a six-inch knife, Lincoln Crown Court was told.
James Cross picked up the knife during an argument at the couple’s home and initially began to harm himself.
Stuart Lody, prosecuting, said Cross smashed a lamp holder with shards of the glass hitting his partner.
Mr Lody said “The argument developed over a period of hours. While the defendant was using the knife to self harm his partner punched him repeatedly to make him drop the knife.
“She ran out of the house into the street. He picked up the knife and went after her.
“He was seen to be chasing her with the knife. He appeared to be foaming at the mouth as he was so agitated and angry.”
Cross (22), of Chestnut Terrace, Sutton Bridge, admitted possession of a bladed article in a public place on March 24, 2012.
Joanne Staples, defending, said Cross had mental health issues and asked for a delay in the sentence to allow for him to be further assessed.
“He has been on bail since this offence and has not been in trouble since.”
Judge Sean Morris adjourned sentence to a date to be arranged so that a further report can be prepared on Cross but warned “At the moment he is looking at an immediate prison sentence.”
