Loyalists tonight threatened to step up their protest outside a Catholic primary school after eight men were arrested.
Protestants accused the RUC of bias in dealing with the stand-off near the Holy Cross Primary School in north Belfast.
Six of the men will face public order charges at a court in the city tomorrow.
North Belfast Assemblyman Mr Billy Hutchinson warned: "It's now made people angry and people will want to up the ante in terms of the protest."
Police arrested the eight as Northern Ireland regional development minister Mr Maurice Morrow announced a regeneration package worth nearly £9 million sterling for the Glenbryn area. But the RUC move has hardened loyalist attitudes.
Mr Hutchinson, a member of the Progressive Unionists who two weeks ago said he was ashamed to be a loyalist following a blast bomb attack yards from where children were passing, added: "I don't blame people, in fact the police are not welcome here for what they have done.
"I think they have been totally biased and acted in a biased behaviour since they came in here on September 3rd."
The protest in Ardoyne Road has continued since the new school term began two and a half weeks ago.
Violent clashes between riot squad officers and loyalists included the blast bomb attack on police lines.
Catholic mothers and fathers escorting their children to class have also endured a daily barrage of whistling, fog horn blasts and sectarian abuse as they return home.
Loyalists protesting at being blocked from access to shops in Catholic areas have staged silent protests as children walk past.
But following today's arrests, stone-throwing incidents involving loyalist youths were reported after parents returned through police lines.
Earlier Mr Morrow announced a urban renewal plan to invest £8.7 million into the Glenbryn area as part of the ongoing strategy for regenerating housing stock in north Belfast.
He said: "Addressing housing needs will not solve the multiple social problems which exist, (but) the provision of good quality housing is essential in improving the life of those experiencing social deprivation."
The Democratic Unionist minister also launched a North Belfast Housing Partnership which will deliver 1,750 new homes over seven years in predominantly Catholic areas.
But Sinn Féin's North Belfast Assembly member Mr Gerry Kelly described the cash injection for the loyalist estate as a "reward for bigotry".
"The perception will be that Glenbryn is going to benefit from an £8.7 million urban renewal scheme as a result of the sectarian blockade of the young schoolgirls going to Holy Cross Primary School."
