A group of people claiming to be supporters of NPP National Chairman Paul Afoko has clashed with the party’s private security, Invincible Forces, over control of the party’s headquarters.

The Forces stuck to their vow made last week to keep out the party Chairman and General Secretary from the headquarters following the death of the Upper East regional chairman, Adams Mahama.

The NPP is in crisis with unprecedented pressure on Paul Afoko and Kwabena Agyepong to step aside.

Regional Chairmen, MPs, members of the NPP Council of Elders are all mounting pressure on the troubled two to step aside but they are unyielding. 

In yet another incident that will further deepen the crisis in the party, the supporters of two factions emerging in the party clashed again at the headquarters Thursday afternoon.

The private security men, Invincible Forces, have not been idle in the crisis but have had their resolve tested by some youth numbering 50.

The youth who were chanting pro-Afoko slogans, attempted taking control of the office but were repelled by about 30 able-bodied men armed with horse whips, Joy News' Kwakye Afreh-Nuamah reported.

In a stone-throwing assault, the two groups exchanged missiles Thursday but the youth proved no match for the invincible forces.

Two of the pro-Afoko group were injured and the windscreen of two buses have been damaged.
