We report the detection of a wide young hierarchical triple system where the primary has a candidate debris disc .
The primary , TYC 5241-986-1 A , is a known Tycho star which we classify as a late-K star with emission in the X-ray , near and far-UV and H \alpha suggestive of youth .
Its proper motion , photometric distance ( 65–105 pc ) and radial velocity lead us to associate the system with the broadly defined Local Association of young stars but not specifically with any young moving group .
The presence of weak lithium absorption and X-ray and calcium H and K emission support an age in the 20 to \sim 125 Myr range .
The secondary is a pair of M4.5 \pm 0.5 dwarfs with near and far UV and H \alpha emission separated by approximately 1 arcsec ( \sim 65-105 AU projected separation ) which lie of 145 arcsec ( 9200–15200 AU ) from the primary .
The primary has a WISE 22 \mu m excess and follow-up Herschel observations also detect an excess at 70 \mu m. The excess emissions are indicative of a 100–175 K debris disc .
We also explore the possibility that this excess could be due to a coincident background galaxy and conclude that this is unlikely .
Debris discs are extremely rare around stars older than 15 Myr , hence if the excess is caused by a disc this is an extremely novel system .
