North Melbourne's Tarryn Thomas has been stood down again

North Melbourne midfielder Tarryn Thomas has been stood down by the AFL club again.

Thomas must remain away from the AFL club and is not available for selection at either senior or VFL level after the Kangaroos determined he had failed to make "sufficient progress" in his respectful behavior education program.

The club was also made aware on Tuesday of further allegations of "inappropriate behavior" from Thomas, which they have shared with the AFL's integrity unit.

Thomas, who only returned to Arden Street late last month, has reportedly been accused of sending more threatening texts to women.

Football boss Todd Viney stressed the latest allegations were not behind the standing down.

"Tarryn will be unavailable to play for the North Melbourne Football Club in the VFL or AFL,"

Viney told reporters at Melbourne Airport on Friday.

"This decision has been made on the back of the education program put in place over the last eight weeks.

We've seen some improvement in some of the understanding and accountability around that program we put in place.

"Unfortunately, (he's) still not quite at the level that he needs to be and that's been our own observations but also the observations from the key providers of some of those services we've put in place.

"So Tarryn's still got some work to be done in that area before he's available to play for the football club.

"Second to that we are aware of the new allegations that are against Tarryn.

"So this is a serious concern to us again, it's with AFL Integrity, we're aware of some of those allegations but with respect to and consideration to the victim of these allegations, we're not at liberty to say too much around those details out of respect for her."

Thomas spent time away from the club last month after being charged in January with threatening to distribute an intimate image. That case is yet to be heard. Earlier this month the 22-year-old faced court on two charges of violating a court order, but those charges were subsequently dropped.
