A Nigerian man is facing a "significant" prison sentence after he spat blood in a police officer's eye.
Temisan Oritsejafor, 41, attacked PC Napier who was arresting him after he assaulted his neighbour.
Police were called to his flat in Wyken, Coventry, on April 18 after he became abusive towards neighbour Alison Osborne.
During the incident, Oritsejafor suffered a bloody nose and while he was being arrested he spat in PC Napier's face.
A court heard Oritsejafor was on bail at the time for a previous assault on a police officer.
Oritsejafor admitted common assault and two charges of common assault on emergency workers at Warwick Crown Court.
Judge Andrew Lockhart QC said: "He is charged with two assaults on emergency workers, one of them while on bail.
"He must understand the sentence will be one of significant custody.
"I will be minded to pass deterrent sentences, and the sentence for the second matter is likely to be consecutive."
Oritsejafor, who was appearing via a video link from the prison, told the judge: "I didn't mean to spit in her face."
But the judge told him: "It is very likely you will be receiving a significant custodial sentence for these matters."
Prosecutor Mark Phillips said: "A male officer who believed he was being aggressive took him to the floor, and was assisted by a female colleague, PC Napier, to restrain him.
"As they're getting him up, he spits into the officer's face.
"That is spit and blood, because he had had a bleeding nose earlier, and it catches her straight in the eye."
Playing a CCTV recording of the incident, Mr Phillips added: "She is clearly upset, and she's very shaken indeed."
Oritsejafor was remanded in custody and will sentenced at a later date.
