LAP Getting aggressive all of a sudden

[Tropex]

I came across this hand in 6-max recently:
PokerStars 0.50/1.00 Hold'em (6 handed) pokerhand.org hand converter

Preflop: Hero is BB with A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, MP calls, <font color="#CC3333">CO raises</font>, <font color="#666666">2 folds</font>, <font color="#CC3333">Hero 3-bets</font>, MP calls, CO calls.

Flop: (9.50 SB) 6[img]/images/graemlins/spade.gif[/img], 7[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, MP calls, CO calls.

Turn: (6.25 BB) T[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, MP calls, <font color="#CC3333">CO raises</font>, Hero calls, MP calls.

River: (12.25 BB) 4[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
Hero checks, MP checks, <font color="#CC3333">CO bets</font>, Hero calls, MP calls.

Final Pot: 15.25 BB

Should I have folded or raised more when the Loose CO went on a rampage all of a sudden. I figured he might have KT or something.

i'm pretty sure this wasn't meant to be posted in the no-limit forum (or maybe i'm accidentally in the wrong forum this morning, heh)

Lol, very true, sorry about it. I was kinda searching for the thread afterwards before I found it [img]/images/graemlins/laugh.gif[/img]

wrong forum:
3-bet the turn, call river?? your line isn't bad it turns out to cost u the same and u bring MP along when u r ahead.
