A FOURTH arrest has been made in connection with the murder of Alan Wood.
The 20-year-old man, from Hampshire, was arrested in the Hampshire area.
He has been bailed until March 1, pending further inquiries.
The arrest came a week after three other men were bailed for a second time in connection with the investigation.
The 35-year-old, 43-year-old and 18-year-old are due to answer bail again on February 7.
Mr Wood was found dead at his home in Lound, near Bourne, on October 24, 2009.
Police believe he was tortured before his death for his PIN numbers to bank cards.
No one from Lincolnshire Police was available for interview.
