(Adds Alstria statement)

July 21 (Reuters) - German real estate company Alstria Office REIT AG said on Wednesday it was aware that Canadian investment firm Brookfield might be exploring a potential takeover offer.

Alstria is currently not in negotiations with Brookfield about a potential takeover offer, it added.

Bloomberg News earlier on Wednesday reported here that Brookfield was working with advisers to evaluate a potential bid, sending Alstria's shares 9% higher.

Alstria owns about 120 office properties in major cities including Hamburg, Frankfurt and Berlin, where workers are returning as Germany eases its COVID-19 lockdown measures.

The company has a market value of about $3.56 billion, with Brookfield having an 8.35% stake as of July 1.

Brookfield declined to comment.

Last month, Brookfield had agreed to buy UK-based infrastructure services company Modulaire Group for $5 billion. ( (Reporting by Ankit Ajmera in Bengaluru; Editing by Ramakrishnan M. and David Evans)
