Nine police officers were injured over a 48-hour period in Derry and Strabane.
In some cases, officers endured racial and sectarian abuse.
On Friday evening while apprehending and arresting a man who was wanted for driving-related offences, an officer was punched to his face.
Four officers were also assaulted while responding to two separate disturbances at house parties in Derry City and Strabane yesterday evening.
During these reports, officers were faced with high levels of aggression – during one of which, a woman ran towards an officer with a knife.
The assaults ranged from officers being head-butted and kicked to the leg – blood was also spat at them.
Two more officers were also assaulted when they responded to a report of a large fight in Derry City involving a number of people.
When officers attended, they were met with a large crowd of people, some of whom became aggressive towards them and an officer sprained her wrist during the restraint of a man, and another officer was kicked to the head.
Due to the level of aggression, officers drew their batons and shouted warnings to the crowd to disperse.
Another officer was also kicked to the head while transporting a woman to custody who was alleged to be involved in an earlier assault in the Strabane area.
“While a man was being placed into custody at Strabane, he also head-butted an officer.
The PSNI says the attacks are “shameful” and there are number of people in custody today who are facing a potential court appearance as a result.
