Sinn Fein assembly member Alex Maskey has said his party will not withdraw support for policing after Gerry Adam's arrest and detention but will continue to "monitor and review" its relationship with the Police Service of Northern Ireland (PSNI).
Mr Maskey said the people he represents are "scathing in their anger" at the PSNI, who he accused of losing the respect of the local community by holding Mr Adams in connection with the 1972 murder of Jean McConville.
He told BBC Radio 4's Today programme: "We have a small element of people involved in policing who are politically motivated, who have a hostile attitude to our party, who have been taking very retrograde steps in relation to how they deal with policing."

The attack happened near the City Cemetery in the west of the city, a Police Service of Northern Ireland (PSNI) spokesman said.

A Police Service of Northern Ireland spokesman has said:
A number of businesses and streets in the Cathedral area of Belfast have been cordoned off following a small explosion.
It occurred at about 6.45pm as police were checking reports of a suspicious object.
At this stage there are no reports of any injuries.
Streets were closed and buildings had to be evacuated after an explosion in Belfast City centre last night, according to reports.
The incident took place on Victoria Street in Belfast city centre, where police were earlier dealing with a suspect vehicle, according to the Belfast Telegraph.
The Police Service of Northern Ireland evacuated the area while they examined the car near the Victoria Square shopping centre, before a loud bang was heard.
The incident began from around 9.30pm on Sunday night.

PSNI Detective Chief Inspector Richard Harkness said: "A number of men were seen running away from the Toyota Camry car."
He added: "I would also appeal to people in Cookstown to think about what they saw in the days and weeks before David's murder last year. Did you see any unusual activity around David's home or the places he frequented?
"I would remind people there is a reward of up to £10,000 available for information leading to the arrest and conviction of those responsible."
In a statement released tonight the PSNI claimed the blast bombs were thrown by masked men in the Lower Newtownards Road area.

This nail bomb was not only a deliberate attempt to further inflame tensions in this area but was an attempt to cause death or serious injury. Fortunately despite this indiscriminate weapon exploding, no injuries were sustained.
Local people have already suffered enough as a result of the trouble within the area. There is absolutely no justification for violence from any quarter, and I would hope that this incident will be treated with the utmost seriousness.
Theresa Villiers, Secretary of State for Northern Ireland, also condemned the "deplorable attack" on police officers.
