We observed the XRT position of GRB 160131A discovered by Swift (Page et 
al., GCN 18951; Goad et al., GCN 18958) at 15 GHz with the Arcminute 
Microkelvin Imager (AMI-LA) on 2016 Feb 24.79 UT and Mar 06.79 UT, 
corresponding to 24.5 days and 34.5 days post-burst respectively. We do 
not detect any radio source at the XRT location, with 3sigma upper 
limits of 150 uJy and 210 uJy respectively.

We thank the AMI scheduling team for carrying out these observations.
