Osano started his career at Reading before a spell with Rushden
Luton Town have extended the contract of defender Curtis Osano until the end of the season.
The 24-year-old Kenyan has played 12 league games this term after
signing an initial six-month deal in the summer
, following his departure from Rushden.
Hatters manager Gary Brabin told
the club website
: "Curtis has been excellent for us.
"He's a great athlete, has bags of enthusiasm, is a hard-worker and loves to get forward."
He added: "We were surprised in the summer that nobody else was interested in taking him on because last season he was fantastic for Rushden.
"I said at the time it was a major coup for us and his form so far has demonstrated what a good player he is."
