Nine police officers have been injured over a 48-hour period in Derry and Strabane.
The officers were injured while on duty between Friday and Sunday.
The incidents included officers being headbutted and being charged at with a knife.
In some cases, the Police Service of Northern Ireland (PSNI) said officers also endured racial and sectarian abuse.

“All of the injured officers remained on duty however, which is testimony to their resilience during the difficult challenges they face on a daily basis, while working to keep people safe,” area chief inspector Luke Moyne said.
“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.”
“Assaults ranged from officers being headbutted and kicked to the leg – blood was also spat at them,” Mr Moyne said.
“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.”
An officer sprained her wrist during the restraint of a man, and another officer was kicked to the head.
Mr Moyne added: “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.
The headbutt incident occurred while a man was being placed into custody in Strabane.
“All of these shameful attacks on our officers will be investigated rigorously – and we have a number of people in custody today who are facing a potential court appearance as a result of their disgraceful actions,” Mr Moyne said
“Officers put themselves on the front line to help keep people safe – they do not deserve to be assaulted for simply doing their job.
“We are supporting these officers following a very difficult weekend. They are receiving the appropriate care and our welfare support has been set up.
“However, assaults across this weekend from just one policing district in Northern Ireland, shows the often grim reality of what our officers on the ground are facing each and every day, and the courage and professionalism with which they serve our communities.” – PA
