  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 ~125 Myr range. The
secondary is a pair of M4.5+-0.5 dwarfs with near and far UV and H\alpha\
emission separated by approximately 1 arcsec (~65-105 AU projected separation)
which lie 145 arcsec (9200-15200 AU) from the primary. The primary has a WISE
22 micron excess and follow-up Herschel observations also detect an excess at
70 micron. 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.
