Three officers have been attacked, with two hospitalised as a result of their injuries.
The attacks happened on the day figures were released showing that assaults on officers in Sussex have risen by 16 per cent during the last four years.
Deputy Chief Constable Jo Shiner said: "Working for the police can be a dangerous and unpredictable job and every day our brave officers and staff work hard, often in difficult and challenging circumstances, to keep people safe.
"Being assaulted while they are doing that is completely unacceptable and must never be seen as part of the job."
In the last four years, assaults on officers in Sussex have risen by 16 per cent with 1,033 being recorded in 2018/19 - an average of three a day.
Of these, 288 resulted in injuries and included kicks, punches, scratches and bruising, through to more serious incidents such as dislocations, fractures and concussion.
Additionally, officers are regularly subjected to being spat at, which in many cases leads to them having to undergo a worrying wait following HIV and hepatitis tests.
On Thursday evening (August 15), two officers attended an address in Hove to conduct a welfare check where suspected 'cuckooing' was taking place.
They were both attacked, with one of them being punched several times to the head, resulting in concussion.
He was taken to the Royal Sussex County Hospital where he remained overnight.
During the fracas, his colleague's knee was dislocated and she was also taken to hospital, where the injury is to be assessed for a suspected hairline fracture.
A 23-year-old man was arrested on suspicion of wounding or inflicting grievous bodily harm without intent and remained in custody on Friday lunchtime.
Elsewhere in the city, a wanted man was spotted walking in New Road on Thursday morning. While he was being detained, he allegedly became aggressive and abusive.
A 35-year-old man of no fixed address was arrested on suspicion of common assault of an emergency worker, assault by beating of an emergency worker, a racially aggravated public order offence and failing to appear in court. He also remained in custody on Friday.
DCC Shiner said: "Since 2017 we have worked with the Police Federation, the Superintendents' Association and Unison to get a better picture of how many officers are being assaulted as many were just shrugging off minor and sometimes more serious incidents and not reporting them.
"Every day officers go out on the frontline to protect the public and this often means helping them at times when they are going through or find themselves in challenging or difficult situations.
"While distressing, this does not give anyone the right to physically or verbally assault our officers or staff. If anyone in force is assaulted while on duty the impact can be both physically and psychologically significant. Not only is that individual affected, but also their team and their family.
"While assaults on officers and staff do occur, we are committed to doing everything we can to reduce these. However, when they do happen, we will do all that we can to support those affected.
“We believe a significant majority of the public would also support that message and hope that an assault on any emergency worker will be seen as the crime that it is and completely unacceptable.”
Matt Webb, chairman of the Sussex Police Federation, said: “Every day my members, the rank and file officers of Sussex Police, go out to serve our communities, to protect the vulnerable and to prevent harm.
"An assault on any one of them is an assault on society and should never be seen as part of the job. No other profession would be expected to accept such an attitude; and neither should we.
"We continue to work closely with the Force to ensure when these incidents occur individuals are supported and seen as the ‘victims of crime’ that they are. We have taken huge steps forward in this area in recent years and will continue to work together to improve the situation further.
"For a number of years we have lobbied for greater protection for police officers, and others, and last year saw The Assaults on Emergency Service Workers Bill gain Royal Ascent and become law – giving magistrates greater sentencing powers.
"However, there remains work to be done to ensure that offenders are always charged with the correct offence, the offence that reflects the level of the assault, to ensure proportionate and appropriate sentencing powers are available to the courts. It can never be right, especially when officers are seriously injured, that offenders are back on the streets before the officers are.”
