Gang man's Facebook message from jail

A patched King Cobra gangster in jail on firearms charges has been posting messages on Facebook from his cell.

Daniel Vae, 32, was on the run and considered by police to be armed and dangerous, unpredictable and high on P before his arrest in July.

Detectives found a silenced semi-automatic handgun, an illegally imported 50,000-volt Taser, a bulletproof vest, methamphetamine gear and his gang patch at his Mt Roskill home.

The semi-automatic pistol was "chopped down" from a 5.56 semi-automatic rifle.

Vae has since pleaded guilty to possession of the taser and firearm and will be sentenced in February.

He is in custody and shares a Mt Eden prison cell with a KC associate, who uses a cellphone to update his Facebook page, with messages from "Danny V".

A photo on Facebook shows Vae making a gang sign while holding bourbon and cigarettes.

One post is a rap rhyme, another an expletive-laden rant against the police.

"Danny V sez f#*k u all, shootem up matherfu#*kaz F.T.P lol ..."

Police fear that a turf war between gangs, Asian organised crime and street dealers could result in spilled blood, as criminals increasingly arm themselves in a bid to control Auckland's drug trade.

Vae became a police target because it was believed he was "taxing" rival methamphetamine dealers selling drugs near the King Cobra headquarters in Ponsonby.

The Facebook revelations come soon after two prison guards were charged with smuggling drugs, phones and cigarettes to inmates last week.

The pair, aged 31 and 33, were arrested after a joint operation between the Corrections Department and police.

They appeared in court and were given name suppression.
